The only “true” thing about Christianity is, that if y’all ain’t my particular denomination, or my particular church, y’all ian’t a true Christian!”
That very point of hypocrisy, in spades, was added to the equation of why I left Pentecostalism.
I can understand that. I worked with a lot of christians who did seem to spend a lot of time making sure that the other christians they rubbed elbows with were “true believing”.
In the Catholic Church the sacrament of Confession gets rid of that concern by focusing one on one’s own spiritual condition, with the goal to stop particular sins and eradicating predominant faults. It is a wonderful sacrament.
