The title gleaned from Ernest Wieman's The Source of Human Good. A dualistic idea: two objects of worship: God and man. At the Council of Nicea a man was pronounced God.
Two kinds of worshippers: those who have absolutized their faith and those who know better. Jesus prayed that we may become one; that's a hard ticket to buy, a hard matter.
Mohammed, Buddha, Jesus: the founders of the great human faiths of the world. The first two did not make the mistake of deifying their man.
Some of us worship the man (or Man); for others he may be a role model (if any man will come after me let him deny himself, and take up his cross, and follow me. Friend and friend Tom Fox may well fit that category, while most of us follow "at a great distance").
The problem with "deifying their man": it leads to war; Christians are the most warlike people the world has ever known. Moslems a close second. Siblings, there is a problem here- an issue as you young folks call it. Can you kill in Christ's name? Can you kill in Mohammed's name?
Thou wilt keep him in perfect peace, whose mind is stayed on thee. That wasn't said about Christ or Buddha or Mohammed; it was said about God.
Shortly after the Council of Nicea the victorious "Christians" were at war with the Arians (who also called themselves "Christians"). Most of the European missionaries were Arians, so the Christians of Europe became Arians. Then there were oceans of blood- between Christians and Christians- over a matter of theology.
(Small wonder that multitudes today have no use for theology.)
Likewise Islam: a highly 'evangelistic' faith; like Christians they conquered both with words and with the sword until there were two billion of them; they learned it from the Christians. They have never called Mohammed God; they simply said he was the last prophet (there could be no more: we must hereafter worship the past.)
Worshipping the past, worshipping God-Jesus; worshipping the last prophet or perhaps only his words. This is the worship of the Created Good.
The worship of the Created Good builds cathedrals and mosques, and empires and war. The worship of the Creative Event, the absolute (unknowable) God builds love, joy, peace.
Exclusivisn on the face of it is sub Christian, sub Islam. Mohammed told his followers to respect the people of the book. Jesus told us to love our 'enemies'. Perhaps most of the followers of both men have done it, in their hearts. Unfortunately the priests, the fanatics have too often called the shots.
To love your enemies deals a fatal blow to the tribalism that has melded you into your in group. To love your enemies changes you into a human being.
