Traditionally Catholics don't proselytize. In the south it is quite common for Catholics to marry Protestants. Catholics know that no one should convert to Catholicism for marriage reasons only; they must truly desire to be Catholic. Therefore Catholic spouses don't proselytize their non Catholic spouses.
In ecumenical settings priests, bishops and popes preach what is held in common and never proselytize in those settings.
Most Catholics in the south have been proselytized by fundamentalists. We don't like it and it creates ill will.
Does anyone suggest that Catholics should proselytize like fundamentalist Protestants, including the Pope? Just wondering.
