First, how did you come up with the "rule" in the first place? Second, how do you come up with what I think? Serious questions.
As I mentioned before, I have strong belief in the power and strength of the Holy Spirit who meets people where they are. We met up in the Catholic faith and the journey began there.
I did not jump to the conclusion that the Holy Spirit only worked through the Catholic Church/faith. My conclusion, based on family, friends, colleagues, is that the Holy Spirit meets everyone where they are, and with the willing, works from there. I don't believe I am that unique.
So, no, I don't believe Catholicism is the religion God wants me to follow. I have an entirely different take on that. I believe God points to the treasures in any faith and each person grows from there. I further believe that faith and religion are almost always about aiding our journey through this life, that the afterlife is more a byproduct of what we learn here.
I have neither the time nor the capacity for an in depth study on every faith, every sect. So I settled on Catholicism because (I feel) there is more depth in Catholicism than any other Christian sect I've given cursory study to. Catholicism has its roots in Judaism so that is my secondary in depth study--so much so if I were forced to choose another sect in would not be a Christian sect (outside of Orthodox), it would be Judaism. That is my selection for me, not direction/choice from God. I have all the faith there is that God can, when the choice is ours, work from there.
In my opinion, you want to limit God to one faith, one religion. You appear to have no belief He can work with all. You seem to limit God to one selection. The difference between us is that I place no limits on God and what He can accomplish no matter how diverse the circumstances or how many the selections.
