I believe that what the Church teaches us about God is without error in her traditional ex officio pronouncements, and that she, as Ignatius of Antioch says, possesses the charism of truth.
I believe that God has granted the church other charisms too, and seeks the salvation of Man, through her ministry. I so believe that all that salvation which there is for man to have, flows from Christ’s Body here on Earth, aka his Church.
Does that make God a Catholic in the same way the pope is Catholic, or I am Catholic? No.
But I think the above is more the point.
