This was my situation at one time. I was formerly a Baptist and I was brain washed into thinking everything bad about the Catholic faith. But as I read the New Testament I discovered verses that my Baptist faith would twist to ANOTHER meaning altogether. Such as being baptized for the remission of sins, Jesus' words of this IS my flesh and this IS my blood. I asked questions to my Pastor and my SS teachers and I got answers that spoke CONTRARY to just what these scriptures actually said.
This led me to examine just what the early Christians believed about baptism and the Eucharist in the early centuries of the church. I got a CD with the early church fathers and boy was I SHOCKED!!! The early church held exactly to what the Catholic faith basically teaches today on water baptism, the Eucharist, penance, and other teachings. They did not teach Baptist doctrines at all.
This is what really turned the tide for me. I later attended RCIA classes and was confirmed and was welcomed into the Catholic church. Now I have real peace, knowing that I belong to the church that teaches and defends what the early church has from it's inception.
When you come to this STRONG conviction and have examined these truths for yourself, you will care less what relatives or other people think. You will want to come home. If you want to email me, just drop me a email. I will be there for you and I will pray for you.
