Let’s use words to mean what they mean. Did not Jesus and his disciples proselytize. that is preach with the goal of converting, changing the hearer’s viewpoint from either pagan religions or from the Jewish religion to another viewpoint, that of Christianity?
How were they disrespectful of their hearer’s intellect? In fact Paul said to Agrippa that conversion of him was Paul’s hope. (Acts 26)
Paul evidently didn’t accept the notion that all roads lead to the good.
In modern times, “proselytism” has acquired the meaning of disrespectful, aggressive, intrusive, crass propagandizing. This was the sense in which the Pope was using the word.
In the Catholic world (and the Pope is a Catholic), the term used for respectful sharing of the Gospel, which includes teaching by quiet example, is “evangelization.”
