What about the part where the Bible tells them; “Do not foresake the gathering together of the bretheren?”
Or John 6:53 when Jesus said, “Amen, amen, I say to you, unless you eat the flesh of the Son of Man, and drink His blood, you do not have life within you.” Are they saved if they do not have life within?
Also the Bible is the “Written Tradition” of the Catholic Church. God has revealed much more. They are missing the “Oral Tradition”, and “Sacred Traditions.” 2nd Thessalonians 2:15 “Therefore brothers, stand firm and hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours.” also 1st Corinthians 11:2
Additionally their Bibles also teach in 2nd Peter 1:20, “Know this first of all, that there is no prophecy of scripture that is a matter of personal interpretation.” and also “…there are some things hard to understand that the ignorant and unstable distort to their own destruction.” So where do they go to learn authentic interpretations? The Catholic Church, which lived the new testament, wrote it under the direction of the Holy Spirit, compiled it into the Bible, and gave it to the world! The Bible is Catholic teaching.
1st Timothy 3:15 …"you should know how to behave in the household of God, which is the
church of the living God, the pillar and foundation of truth." What is the very foundation, and support of the truth? The Catholic Church, not their personal opinion.
Do they not know that when the Bible says “Church” it is referring to the Catholic Church? Or do they think the Bible fell from the sky? Some people have never thought about this. I hope this helps.
