For context, the Pope said:
Dear brothers and sisters, we are never alone. We can be far, hostile; we can even say we are ‘without God.’ But 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!
True, God became a man and was united to our human nature by the Second Person of the Blessed Trinity. Jesus Christ did so out of love for our souls and to save us, not because His Divinity in the Godhead depended on us. God is infinite perfection. He created us out of His goodness and love so that we might one day share in His eternal happiness and perfection.
The Council of Florence teaches, "the one true God, Father and Son and Holy Spirit, is the creator of all things visible and invisible, who, when He wished, out of His goodness created all creatures, spiritual as well as corporal” ~Bull Cantate Domino
The Pope's error was explicitly condemned by the Fourth Lateran Council and Vatican I:
This sole true God by His goodness and “omnipotent power,” not to increase His own beatitude, and not to add to, but to manifest His perfection by the blessings which He bestows on creatures, with most free volition, “immediately from the beginning of time fashioned each creature out of nothing, spiritual and corporeal, namely angelic and mundane; and then the human creation, common as it were, composed of both spirit and body [Fourth Lateran Council].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. [Vatican I, Dogmatic Constitution Dei Filius]
This heresy to me seems to be a form of pantheism, which puts God and the world on par with each other as one. The Syllubus of Errors condemned the idea that we are all gods, subject to one another, bringing the Supreme God down to our level, dependent on us for His Divinity and Rights. Is it any wonder that Pope Leo XIII proclaimed that we need to hear more of the rights of God and not man? Alas, we all are well aware that Christ the King was dethroned from His Church, while the whims and wishes of modern man are glorified, extolled and encouraged. These words of the Pope are just yet another fruition of the Modernism that has ravaged the Church this past century.
Condemned in the Syllubus:
"There is no supreme, all-wise and all-provident Divine Being distinct from the universe; God is one with nature and therefore subject to change; He becomes God in man and the world; all things are God and have His substance; God is identical with the world, spirit with matter, necessity with freedom, truth with falsity, good with evil, justice with injustice"
If not for God, the entire world and all the souls in it would disappear instantly. It's not vice versa. The Holy Father should go back to seminary, a Catholic one that is and learn the religion, instead of spouting off every opinion of his from his personal magisterium. May the Holy Trinity open his eyes from the Modernist poison that he has been a victim of and convert him to the Catholic Faith so that his words and guidance will save souls and be a bulwark of the truth.
