I stay away from interdenominational issues. I am Catholic; I am only interested in explaining what my faith is and why.
I am not doubting your sincerity or intent, but this kind of post just seems to invite yet another “my denomination is better than your denomination,” which are generally not constructive discussions.
With rare exceptions, protestants of every type, to Roman catholics, to Anglican Catholics, to Messianic Jews (me) agree on 99.94% of theology.
If only more time was spent on the rest as that .06%, the greater Christian Church would be much better off.
The sibling I am closest to, spiritually speaking, is a practicing Catholic. I'm a Calvinist -- someone who processes Protestant convictions through Catholic hard wiring. Something about being raised a Catholic predisposes one to seeking global implications for his faith.
For me, as much as I respect my beloved fellow Christians of the Roman communion, the cult of the BVM is an insuperable barrier on the road back to Rome.
Meanwhile, I am grateful for the vast majority of theology and conviction we have in common.
