Oh dear! Paul’s proselyting must have had “a disastrously bad effect on evangelism” when he argued in the Areopagus.
(Acts 17)
What Paul did in the Areopagus wasn't proselytizing in this modern derogated sense. He didn't offer tangible bribes in exchange for conversion (housing, jobs, medical care, food). He didn't recruit children without their parents' knowledge or consent. He didn't use emotional manipulation. That is proselytism. He went to a forum and made a straight, honest and persuasive appeal to his fellow citizens. That is evangelism.
