| Objective, Primary [Text Block] | oef_ObjectivePrimaryTextBlock | The Venerable Bond Index Fund (the "Fund") seeks to replicate the performance of a benchmark index that measures investment grade bonds traded in the U.S. as closely as possible before the deduction of Fund expenses. |

| Expense Heading [Optional Text] | oef_ExpenseHeading | Fund Fees and Expenses | ||||||
| Expense Narrative [Text Block] | oef_ExpenseNarrativeTextBlock | This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Fund. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies ("Variable Contract"), which are not reflected in the tables and examples below. If these fees or expenses were included in the table, the Fund's expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract. |

| Expense Example Narrative [Text Block] | oef_ExpenseExampleNarrativeTextBlock |
This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The example does not reflect expenses and charges which are, or may be, imposed under your Variable Contract. If the example were to reflect the deduction of such charges, the costs shown would be greater. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The example reflects the Fund's contractual fee waivers and reimbursement obligations only for the term of the fee waivers and reimbursement obligations. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be: |

| Portfolio Turnover [Heading] | oef_PortfolioTurnoverHeading | Portfolio Turnover | ||||||
| Portfolio Turnover [Text Block] | oef_PortfolioTurnoverTextBlock |
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in the annual fund operating expenses or in the example above, affect the Fund's performance. During the period September 5, 2025 through December 31, 2025, the Fund's portfolio turnover rate was 27% of the average value of its portfolio. |

| Portfolio Turnover, Rate | oef_PortfolioTurnoverRate | 27.00% | ||||||
| Strategy [Heading] | oef_StrategyHeading | Principal Investment Strategy | ||||||
| Strategy Narrative [Text Block] | oef_StrategyNarrativeTextBlock | The Fund invests, under normal circumstances, at least 80% of its net assets (plus borrowings for investment purposes) in companies that are included in a benchmark index that measures investment grade bonds traded in the U.S. Typically, the actual percentage is considerably higher. The Fund uses an index-based investment approach designed to track the Bloomberg U.S. Aggregate Bond Index (the "Index"), a widely recognized benchmark of U.S. investment grade fixed income performance. The Index includes investment grade, U.S. denominated, fixed-rate taxable bonds. Venerable Investment Advisers, LLC (the "Adviser") has engaged Franklin Advisers, Inc. ("FT") to provide the day-to-day management of the Fund's portfolio pursuant to investment guidelines provided by the Adviser. The Fund will generally employ a stratified sampling approach to build a portfolio whose broad characteristics match those of the Index without purchasing every security in that Index. The Fund's stratified sampling approach seeks to match the return and other characteristics of the Index by selecting a representative sample of component securities for the Fund based on the characteristics of the Index and the particular securities, such as interest rate sensitivity, credit quality and sector diversification. The Fund's securities holdings may differ from those represented in the Index. The Fund pursues a strategy of being fully invested by exposing its cash to the performance of the Index by purchasing index swaps and index futures contracts, which are derivatives. The Fund may concentrate its investments (i.e., hold more than 25% of its total assets) in an industry or group of industries to the extent that the Index is so concentrated. The Fund may acquire securities on a "when-issued," "delayed delivery" or "to-be-announced" basis. These transactions are arrangements under which the Fund buys securities that have been authorized but not yet issued, with payment for and delivery of the security scheduled for a future time. The Fund is classified as a diversified investment company, as defined in the Investment Company Act of 1940, as amended (the "1940 Act"). However, the Fund may become non-diversified under the 1940 Act without the approval of shareholders solely as a result of change in relative market capitalization or index weighting of one or more constituents of the Index. A non-diversified fund generally invests a greater portion of its assets in a limited number of issuers relative to a diversified fund. The Fund may be non-diversified for an indefinite period. |

| Venerable Bond Index Fund | Venerable Bond Index Fund | Fixed Income Securities Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Fixed Income Securities Risk. Prices of fixed income securities generally rise and fall in response to, among other things, interest rate changes. Volatility in interest rates and in fixed income markets may increase the risk that the Fund's investments in fixed income securities could lose money. In addition, the Fund could lose money if the issuer or guarantor of a fixed income security or other issuer of credit support is unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. Fixed income securities may be downgraded in credit rating or go into default. |

| Venerable Bond Index Fund | Venerable Bond Index Fund | Interest Rate Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock |
• Interest Rate Risk. Prices of fixed income securities generally rise and fall in response to interest rate changes. Generally, when interest rates rise, prices of fixed income securities fall and when interest rates fall, prices of fixed income securities rise. The risks associated with changing interest rates are heightened under current market conditions, given that interest rates in the United States and many other countries have fluctuated in recent periods and may continue to change in the foreseeable future. Expectations of higher inflation generally cause interest rates to rise. The longer the duration of the security, the more sensitive the security is to this risk. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Credit Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Credit Risk. The chance that a bond issuer will fail to pay interest or principal in a timely manner or that negative perceptions of the issuer's ability to make such payments will cause the price of that bond to decline. Credit risk should be low for the Fund because it purchases only bonds that are of investment-grade quality. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Mortgage-Backed Securities Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Mortgage-Backed Securities Risk. Mortgage-backed securities may be affected by, among other things, changes or perceived changes in interest rates, factors concerning the interests in and structure of the issuer or the originator of the mortgage, or the quality of the underlying assets. The underlying assets may default or decline in quality or value. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Asset Backed Securities Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Asset-Backed Securities Risk. Payment of principal and interest on asset-backed securities may be largely dependent upon the cash flows generated by the assets backing the securities and asset-backed securities may not have the benefit of any security interest in the related assets. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Financial Markets Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Financial Markets Risk. Global economies and financial markets are increasingly interconnected and conditions (including volatility and instability) and events (including natural disasters, pandemics, and epidemics) in one country, region or financial market may adversely impact issuers in a different country, region or financial market. In addition, governmental and quasi-governmental organizations have taken a number of unprecedented actions designed to support the markets. Such events and conditions may adversely affect the value of the Fund's securities, result in greater market or liquidity risk, or cause difficulty valuing the Fund's portfolio instruments or achieving the Fund's objective. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Derivatives Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Derivatives Risk. Investments in a derivative instrument could lose more than the initial amount invested. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities. The use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in equity or fixed income securities, currencies, or other instruments. Derivatives are generally subject to a number of risks such as leveraging risk, liquidity risk (the risk that the investment cannot be sold quickly), market risk, credit risk, default risk, counterparty risk (the risk that the other party in an agreement will fail to perform its obligations), management risk, operational risk, and legal risk. Certain of these risks do not apply to derivative instruments entered into for hedging or cash equitization, certain cleared derivative instruments, and written options contracts. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative instrument may not correlate exactly with the change in the value of the underlying asset, rate, or index. |

| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock |
• When-Issued, Delayed Delivery and "To-Be-Announced" Securities Risk. When-issued and delayed delivery securities and forward commitments involve the risk that the security the Fund buys will lose value prior to its delivery. There also is the risk that the security will not be issued or that the other party to the transaction will not meet its obligation. If this occurs, the Fund may lose both the investment opportunity for the assets it set aside to pay for the security and any gain in the security's price. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Index-Based Investing Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Index-Based Investing Risk. The Fund uses a stratified sampling approach to attempt to match the return and other characteristics of the reference index by selecting a representative sample of component securities for the Fund based on the characteristics of the reference index and the particular securities, such as interest rate sensitivity, credit quality and sector diversification. The Fund will generally hold constituent securities of the reference index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of the performance of individual securities or market conditions could cause the Fund's return to be lower than if the Fund employed a fundamental investment approach to security selection. Additionally, index-based strategies are subject to "tracking error" risk, which is the risk that the performance of the Fund will differ from the performance of the reference index it seeks to track due to differences in security holdings, operating expenses, transaction costs, cash flows and operational inefficiencies. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Industry Concentration Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Industry Concentration Risk. To the extent the Index (and, therefore the Fund) concentrates its investments in one or more industries, the Fund will carry much greater risk of adverse developments in those industries than a fund that invests in a wide variety of industries. |
||||||
| Venerable Bond Index Fund | Venerable Bond Index Fund | Non Diversification Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock | • Non-Diversification Risk. To the extent the Fund becomes non-diversified, the Fund may invest a relatively high percentage of its assets in a limited number of issuers. Therefore, when the Fund is non-diversified, the Fund's performance may be more vulnerable to changes in the market value of a single issuer or group of issuers and more susceptible to risks associated with a single economic, political, or regulatory occurrence than when the Fund's invested assets are diversified. |

| Venerable Bond Index Fund | Venerable Bond Index Fund | Impact of Large Redemptions (Including Possible Fund Liquidation) Risk [Member] | ||||||||
| Prospectus [Line Items] | oef_ProspectusLineItems | |||||||
| Risk [Text Block] | oef_RiskTextBlock |
• Impact of Large Redemptions (Including Possible Fund Liquidation) Risk. The Fund is used as an investment by certain funds of funds and may have a large percentage of its shares owned by such funds. Large redemption activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions. Large redemptions may also result in increased expense ratios, higher levels of realized capital gains or losses with respect to the Fund's portfolio securities, higher Fund cash levels, higher brokerage commissions and other transaction costs, among other negative consequences such as reduced liquidity in the Fund's portfolio. As a result, large redemption activity could adversely affect the Fund's ability to conduct its investment program which, in turn, could adversely impact the Fund's performance or may result in the Fund no longer remaining at an economically viable size, in which case the Fund may cease operations. |
