Hi, KCMekim,
Glad you asked…

And, thanks for your explanation on SS.
The name “sola scriptura” is actually a little misleading so it’s hard to blame Catholics for not understanding what we believe about sola scriptura.
That’s why I much prefer to say the authority of scripture, rather than sola scriptura.
What else are we to use?
In John 16:12-14 Jesus says to His Apostles
12
"I have much more to tell you, but you cannot bear it now.
13
But when he comes, the Spirit of truth, he will guide you to all truth. He will not speak on his own, but he will speak what he hears, and will declare to you the things that are coming.
14
He will glorify me, because he will take from what is mine and declare it to you.
Even after the Resurrection the Apostles were slow to believe and fearful. Christ rises up into heaven 40 days after His Resurrection - and at least some of the Apostles are slow to believe and fearful. Ah, but then comes Pentecost when the Holy Spirit transforms these slow to believe and fearful followers of Christ who happened to be hiding from the Jews at the tine - into courageous and fearless proclaimers of the Word. Now, you just have to wonder, “How did that happen?”
Well, we have to go back just a bit. Recall in Matt 16: 18 that God the Father gave Peter a special inspiration to declare that Jesus was the Son of God. Peter had not figured this out on his own - rather through Divine Revelation Peter was able to answer Christ’s question correctly. Christ builds His Church (and, that would be the Catholic Church) on Peter. It is this Church that provides us with inerrant teaching (this would be the same Church tht has provided you with the inerrant Word of God - the Bible).
Do you find it strange that John (who ran away the night Christ was arrested) but who stood by the Dying Christ on the Cross with Mary, the Mother of God, did not come up to Peter and say something like, “You are not fit to be our leader. You DENIED the Son of God before men! I’m taking over the leadership of this group because you have sinned and failed the test while I did not!” That didn’t happen - even though Peter did sin by denying Christ - and Christ forgave the repentant Peter… Christ did not fire Peter from his job!
Every Pope since Peter has had the same basic problem: they were all sinful men with real (not imagined) weaknesses as they lead God’s Chruch. You want to see something amazing - well, tracing the line from Christ to Peter to Benedict XVI is really not hard to do… here is a link:
en.wikipedia.org/wiki/List_of_popes But, the really amazing thing is that this Church today is totally recognizable in its teachings. For example:
Baptism - the CC has always taught that this is necessary to be declared a Child of God. The form (sprinkling, pouring, immersion) of how the water is used is not important as long as water is used and the Trinitarian wording is pronounced.
Confession - the CC has always taught that Christ delegated the Power to forgive (or, not forgive) sin to the Apostles who passed this on to their successors.
Holy Eucharist - the CC has always taught it is the Body, Blood, Human Soul and Divinity of Jesus Christ under the appearance of common bread and wine.
If you are looking for something to use to get the Full Story - then pay attention to the teaching of the Catholic Church. Christ promised that the Gates of Hell would not prevail - the CC can not teach error. It is as simple - and as complex - as that.
God bless
