| Performance Narrative [Text Block] | The following bar chart and table provide some indication of the risks of investing in the Fund by showing the variability of the Fund’s performance from year to year and by comparing the Fund’s performance to a broad-based index and an index that is more representative of the Fund’s investment strategy. The bar chart shows the investment returns of the Fund’s Class A shares. These annual returns do not reflect sales charges on Class A shares; if they did, results would be lower. The Fund’s past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. More up-to-date returns are available on the Fund’s website at fund.timothyplan.com, or by calling the Fund at (800) 846-7526. |
