Nope, Colofornian was talking about how silly it would be for a 14y/o boy to teach things about the gospel, things that went against the grain of the established religions of his day.
Evidence shows he never did teach the things about 'the gospel' he claimed to have learned. His family joined the Presbyterian Church and he tried to join a Methodist church. BTW, how old was he really? 14, 15 or 16?
