During his Wednesday audience in St Peter’s Square Francis claimed, “Jesus Christ’s Gospel reveals to us that God cannot be without us. He will never be a God without man. It is he who cannot be without us, and this is a great mystery. God cannot be God without man, this is a great mystery.”
Francis' words correspond to the heresy of Gnosticism (1st and 2nd century AD), which claimed that God needed to create an object for his love because he is imperfect. Catholic doctrine instead confesses a perfect God who is perfect love in a Trinitarian relationship. God created mankind gratuitous out of a superabundance of love not out of a need.
If anyone does not confess that the world and all things which are contained in it, both spiritual and material, as regards their whole substance, have been produced by God from nothing, or, shall have said that God created not by a volition free of all necessity, but as necessarily as He necessarily loves Himself, or, shall have denied that the world was created to the glory of God: let him be anathema.(First Vatican Council, Dogmatic Constitution Dei Filius; Denz. 1783, 1805; underlining added.)
