"The deceiver uses the name of Jesus Christ to lead the weak-minded into all sorts of error. “Judge not lest ye be judged” applies to oneself as well as others. I imagine thinking yourself guaranteed is pride."
Only if you think “the deceiver” is Christ, for it was He who founded the Catholic Church.
If you want disciples of the deceiver, I suggest you look in Geneva or New Jersey.
No. The Church established and protected from error by Jesus Christ relies on the Holy Spirit to continually guide it and keep it free from error, as opposed to continually fragmenting and increasingly heretical protestantism.
