Hi andie72,
You have pronounced judgement on every Christian in the first 1000 years of Christianity
This is not at all so. There were very many other groups of genuine Christians from the beginning of the Church.
Sadly, the Roman Catholic Church is not known for its monopoly on truth, but rather for resisting truth time and time again; and, apart from its historical use of a language foreign to many of its communicants until the 1960s, also, for actively removing the scriptures from its flock.
I hope you take time to do a great deal more research before finally embracing subjection to Papal governance.
Your Master is Jesus Christ, and by His Spirit He is well able to guide you safely through your life in this world, and keep you through the troubles (tribulations) His people necessarily experience. Your Father is in heaven, and the writer to the Hebrews exhorts
9 Furthermore we have had fathers of our flesh which corrected [us], and we gave [them] reverence: shall we not much rather be in subjection unto the Father of spirits, and live? (ch 12)
Matthew 23:9 And call no [man] your father upon the earth: for one is your Father, which is in heaven
There are many other pieces of RCC doctrine which are intransigent to scripture, which rather than obey, they change the scripture.
One of these is the notion that when a baby is christened (baptised), it is 'born again'. According to Paul Washer who preaches in Roman Catholic countries, this is one of the most difficult ideas for a Catholic to give up.
And there are many other legalistic strictures, quite apart from the lie that the death of Christ was not sufficient to atone for our sins, which is promulgated through the liturgy of Mass, and false ideas about works, and what happens when we die.
Please be very very careful.
