William Henry Young
Evangelical Agnosticism (1985)
Tracing the concept back to T.H. Huxley, Young defines "evangelical agnosticism" as the following: "emphasizing a ready willingness to accept the fact that we live without final answers to many questions, encouraging a commitment to consider all possible answers to our questions, and suggesting that it is immoral to advocate answers beyond the extent of our evidence."
There is little doubt that Thomas Henry Huxley invented the word agnostic in the Spring of 1869. However, there is conflicting evidence about when this was and what it originally meant.
