I do want to comment now though on 1John 2:18-20. It is talking about those who leave the Church (the Christian church) prove that they are not a part of the Church nor were they ever a part of the Church. It has nothing to do with the Catholic Church though, or you would be forced to say that I am not a Christian. You aren’t going to do that are you?
In fact, it reinforces eternal security. True believers will never leave, because Christ promises to keep them. Praise God!
You will now have to reconcile what Paul said as he asked for the prayers of the early believers that they pray for him that he not fail.
If Paul was aware that justification was real, was ongoing, and was "lose"able… we should have deep concern too that we continue to work out our salvation in fear and trembling.
and…
would you agree that a “true” believer is one who believes in everything that Christ taught and spoke, and shared, and sworn as true??
if yes, then you now must reconcile that most difficult John 6 with Paul’s admonishment of the literal meaning of the gift of the Eucharist (given only by way of that pesky ministerial priesthood you don’t see in the NT)
if you cannot accept the Real Presence, (what Jesus said, not what Lutherans etc might avow today)… if you cannot accept John 6 then one of four things is happening:
1- The Lord has not chosen this time to open your eyes
2- the non-authoritative leaders you might listen too are teaching you error (on purpose or not)
3- you have succumbed to a fatal self-interpretation of scripture
4- you are not putting your faith to work, by asking God for more faith.
Sola Fide … not true, not scriptural, not workable
Sola Scriptura… not true, not scriptural, not workable
O’ sola meo … true outside the Church, not scriptural,fatal
Sola Dei Verbum… Only the Word of God…
The only sola that will work… and the only Fullness of this Truth can be found in the Catholic Church and the three witnesses to the Truth… Tradition, Scripture, Magisterium
