The Roman Catholic church does not have a leg to stand on -- for most of their teachings are base on books, writings, and traditions which are not found in the Bible.
.
Here's a few for you billy.................
Mt 16: 18-19 -- upon this rock I will build my Church.
Mt 18: 17-18 -- If he refuses to listen even to Church
Lk 10: 16 -- whoever hears you, hears me, rejects you, rejects me
Jn 16: 13 -- Spirit of truth will guide you to all truth
Mt 28: 20 -- I am with you always, until the end of the age
Rom 2: 2-8 -- eternal life by perseverance in good works
Eph 2: 8-10 -- we are created in Christ for good works
Jam 2: 14-24 -- a man is justified by works and not faith alone
Gal 5: 4-6 -- nothing counts but faith working through love
Jn 6: 35-71 -- Eucharist promised
Mt 26: 26 / Mk 14: 22 / Lk 22: 17 -- Eucharist instituted
1 Cor 10: 16 -- Eucharist participation
1 Cor 11: 2 -- hold fast to traditions I handed on to you
There are hundreds more in your Bible billy, the main concern would be
if you believe God will condone changing his Bible for no more of a reason
than a unstable disgruntled priest that wanted to start a different religion, may
not play out the way you think.
