It is evident, indeed, that such a doctrine, taken by itself in a literal manner, had no future. The world, in continuing to exist, caused it to crumble. One generation of man at the most was the limit of its endurance. The faith of the first Christian generation is intelligible, but the faith of the second generation is no longer so. After the death of John, or of the last survivor, whoever he might be, of the group which had seen the master, the word of Jesus was convicted of falsehood.
