It seems that there would soon be a certain code of conduct in trying to win converts to another religion. According to Reuters:
Christian churches are moving closer to a common code of conduct on how they go about winning converts among themselves and from other religions, the World Council of Churches (WCC) said on Monday.
No prizes for guessing whether true Christians would be deemed to have 'violated the code' as we share the Gospel of Jesus Christ which can alone save any person. As for me, I couldn't care less about this 'code'. They don't speak for me anyway.
