გამოცხადება in English:

What a revelation!

The Bible, as a revelation from God, was not designed to give us all the information we might desire, nor to solve all the questions about which the human soul is perplexed, but to impart enough to be a safe guide to the haven of eternal rest.

Abu al-Husayn ibn al-Rawandi, already in the ninth century, held that reason is man's exclusive guide to truth, a quest in which revelation is of no help.
