The distinctions between Biblical Christianity and Catholicism are vast and irreconcilable.
1. The Mass as a continuing perpetual sacrifice of Jesus is unBiblical (John 19:30, Hebrews 9:25-28, Rev 1:18)...And the heresy of "receiving Christ" through "Holy Communion," believing that a priest has the POWER to yank the Lord Jesus Christ out of heaven and put him into a wafer (Transubstantiation)
2. Works added to faith for salvation is not Biblical (Ephesians 2:8-10, Titus 3:5-8, Galations 2:16, Romans 4:4-5)
3. Infant Baptism: From John the Baptist through the book of Acts, only believers are baptized, no exception.
4. Peter as the first 'pope,' the 'rock' on which Christ allegedly established his church: Acts 4:8-12, 1 Peter 2:6-9, Deut 32:3-4, Ps 18:1-2, 1 Cor 3:11. (The 'rock' in Matt 16:18 is found in v 16b - it's the proclamation that Jesus is the Christ, the Son of the living God)
5. Priests vs. priesthood of the believer: 1 Peter 2:9, Rev 1:6, Heb 7:25, Heb 4:14-16
Additionally, Catholics pray to idols and to Mary, and the Bible is explicit about whom to pray to: God alone. Furthermore, prayer for the dead borders dangerously close to necromancy (see Revelation 22:8-9)
I never see Catholics caring enough about others to actually share something about their faith. But in the Bible, Jesus says an amazing thing..."Go ye into all the world and preach the Gospel to every creature." And..."I am the way, the truth, and the life. No man cometh unto the Father, but by me."
The official Catholic position, proclaimed by all the popes for the last 1,000 years, is that salvation is found only in the Catholic church, through the sacraments, by the priests, under the cardinals and pope.
But the Bible says that salvation is only in Jesus Christ. The apostle Peter said... "Neither is there salvation in any other: for there is none other name under heaven, given among men, whereby we must be saved."
Saved from what? Judgment is coming - for you and me - and Jesus preached that most people are on their way to hell...the broad road to destruction. And that the road to life and heaven is narrow and few find it.
