While I do believe there is one God in three persons I havent yet seen proof of that belief being a prerequisite for salvation. Surely the jailer was not in a position to understand that. No indication is given for that to be an understanding for the 3000 who were added understood that. So lets put things into perspective here. Practices, beliefs, and rituals of the RCC are specifically condemned by God. Belief in the concept of the trinity is NOT a prerequisite for salvation. Belief that Jesus paid the complete price for our salvation and that He was the perfect and final sacrifice needed is required for our salvation and that again is something the RCC and its followers have added criteria to.
Denying the sufficiency of Christs sacrifice has a greater affect on ones salvation than not understanding the intricacies of the trinity.
It's not what they are told to believe that they should think twice about - but what they are not taught. They say they must believe in the Trinity; yet they ignore the Holy Spirit, they discount that HE is in us, born again believers, and non stop with their 'our interpretation' all the time in spite of that very teachings of Jesus. I go to prepare a place and He will send The Comforter, The Teacher, the HOLY SPIRIT. And His Word is 'spiritually discerned as it IS Holy Spirit Inspired. Catholics do not believe Jesus nor His Spirit.
They place Mary for Jesus, pray to the dead instead of going directly to the Father - God doesn't have a 'go to' person - HE IS THE PERSON and Jesus offered us a direct link to HIM. That is the reason for Him dying for us to make that possible - as sin separated us from The Father.
Where ever The Trinity should be in their lives, the place it with man. So with their lips they say they believe in The Trinity (because they are taught that) but they do NOT with their heart or actions (because of their teachings). One can't say they believe in The Trinity and then keep discounting IT. That is what they are doing. How many posts did we see from them - telling us that we don't believe in The Trinity?
Another thing - they still have Jesus on the Cross and Mary is with the baby Jesus. Where do they show ANY indication that HE is risen?? And that IS the crux of Christianity. And then they have a pope who brazenly reinforces it with saying 'I'm all yours, Mary' and embroiders it on his garments. There is no denying, Jesus is on the back burner in the catholic church. And JESUS IS part of the Trinity and the three can't be separated. Where Jesus is - is God and HIS Spirit. 'When you see ME, you see the Father.'
JESUS is GOD and not a baby. Jesus IS RISEN and sitting at His Father's right hand. Now 'who' wouldn't want to proclaim that the Man Jesus is GOD reinforced?? - And that HE Resurrected? - now 'who' deceived man that brought sin into the world? what 'loser' would be angry that Jesus came to earth to die for OUR SINS and, then, resurrect to show HE is God for us? 'Who' wants us to keep our sins? What happens to us if we die in sin? Where do we go? That 'who' is behind those teachings and he wants to make the subjects of those teachings 'losers' along with him - where he goes, he wants them there, also.
Bottom Line: Catholics do not believe in The Trinity, The Father, Son and Holy Spirit - only with their lips and that is perfect with Rome and the design/plan of satan. And we nknow MANY will fulfill the plan of satan. And we know the only weapon satan has is deception from the beginning.
Satan is just an imp and a flea has more power than satan. Satan needs a body to perform his evil. Remember the pigs the demons begged to be cast into?
