You cannot be in full communion with the Catholic Church and not submit to the papal office.

Catholics owe the Pope religious submission of intellect and will to his authentic magisterium (teaching authority) on faith and morals, even when not speaking infallibly (Lumen Gentium 25; CCC 892; Code of Canon Law, can. 752). This is a respectful adherence and presumption in favor of what he teaches officially as Pope. This does not extend to his personal opinions, private theological views, prudential judgments (e.g., on politics, economics, or administrative decisions), or liking him as a person or agreeing with everything he says or does in a non-magisterial capacity.
