Allah is not the God of Abraham.
I was speaking , Peter abbey of Cluny speaking of arianism , of Jesus’ God and Jesus as true God and true human as says the Credo !
Abraham is not precisely Jesus Christ and jews who condamned or still reject Jesus Christ are hardly Abraham’s sons .
From another point of view , in other words , arianism is not christian and can be compatible with islam ( islam pretends that Jesus Christ is a prophet for islam undermining his message and life )
