Let me preface with this Yarddog; I believe there are clearly saved souls within Catholicism because The Lord can and will use all means and measures to save souls from hell.
God can do anything, but have no worry, Catholicism is just fine in the eyes of the Lord.
I was in a heretical church,
I certainly don't like to call anyone heretical but I was raised in the Baptist Church until I left as a teenager.
God baptized me in his Holy Spirit a few years later, in my bedroom late one night. God eventually brought me to the Catholic Church and began to reveal the wonders of the sacraments. I have received at least two miraculous healings and numerous events of the Holy Spirit during Mass.
About your questions, Holy Scripture is not tradition,
That is because you don't understand what Holy Tradition means in the Church. You seem to be applying your own understanding to what the ancient Church has established.
Of course I know that it is God's Word.
It is God's "written" word. Jesus is the "Word" of God.
Q?: Why are babies, that cannot possibly understand The Gospel message, baptized?
Because that is what the Apostles did.
Is there a second baptism after an age of understanding and accountability, understanding and acceptance is reached of what salvation is? How does that work in the Catholic church?
There is the sacrament of Confirmation but Catholics do not "re-baptize" anyone who has a valid baptism. Confirmation is the laying on of hands for the sealing of the Holy Spirit.

I've had conversations with people in Catholicism, that believe that their souls are secure because of being sprinkled as a baby and then completing the sacraments.
It is impossible to know what they actually told you or even how much they actually understood about what they said. Regardless of what they do, if they have no faith, we cannot say that they are justified.
The problem rests in the thought and practice that their salvation is somehow tied directly into the Catholic Church and Catholicism's sacrements...
Jesus is tied to the Catholic Church so we can say that they are correct. I'm not saying that he is not also tied to you. Christ is in everything that we do, "but" just as in all Christian Churches, not every Catholic is a good Christian.
when it is only founded on a personal relationship to Jesus Christ as the Son of God,
We have a personal relationship with Jesus Christ and experience Jesus in incredible ways through the sacraments.
who died for our sins, rose again on the third day and is seated at the right hand of The Father....and ever lives to intercede for us. He is our portion, our rock, our salvation.
Reference Mark 16:6...
He that beleiveth and is baptized shall be save but he that disbelieveth shall be condemned...
The point of that verse is that, those that believe will want to be baptized but those that DISBELIEVE are condemned...not those that aren't baptized.
And? If you believe you will get baptized, will you not? Mark says that it is necessary for salvation.
I know I couldn't wait to be baptized when The Lord opened my eyes, showed me the truth of His Word and revealed Himself to me, as my one and only Savior!
Let me punctuate that with this question;
The thief on the cross, did he go to be with The Lord in paradise, that very day as Jesus said he would...or did The Lord lie to him?
The thief wasn't baptized.
Catholics call that the baptism of desire which covers those who desire baptism but cannot have the formal rite.
Let me end with this, my recently passed mother-in-law, whom I loved very much and was one of my best friends, was raised in Catholicism, yet had very little understanding of God's Word.
That occurs in many Christian churches. If she regularly attended Mass, she should have heard the scriptural readings, 1 from the OT, 1 from the Epistles, and 1 from the Gospel, and how they apply to our everyday life and to each other. Usually these reading cover several verses from each section. If she had little understanding, it seems that she wasn't listening very well.
She left Catholicism as she began to truly study The Bible, excluding the "Catholic Bible" and the "Catholic Study Bible" which was interlaced with traditions and explanations from a strictly Catholic point of view.
It sounds like she should have joined a Bible study group at her Catholic Church before she left. She may have understood things better.
I want to be like The Lord, full of grace and truth but the truth cannot be excluded or suffer as a result of an emphasis on grace.
Truth cannot be given if someone doesn't want to hear it. You say that she didn't do the work before she left the Catholic Church. Any Bible study that she received after that would come with the man made traditions of the study group she got into after she left.
Finally, I still see there is significant deviation from God's Word within Catholicism, not the least of which are prayers to Mary, (Mary worship),
Words have several meanings so don't use "worship" in this case as is reserved for God. Do you pray for other people? We do. We also believe that those that God has taken to heaven also pray with us, so Mary and all Saints can pray with us. Asking Mary to pray with us, to God, is what this is.
See above.
the hierarchy of leadership,
Scriptures relates the hierarchy. Were there not elders and presbytery? Were there not apostles and teachers? But not all were called to be each.
Are you not holy? What is wrong with calling the Pope holy? He is a Father in the since that he looks over God's children. Jesus called Peter to feed his sheep. There wasn't very many sheep then but he was talking about everyone in the Church including the other apostles. Holy Father is a title. Don't read too much into it. We don't worship the Pope or believe that he is divine.
and traditions overriding the unfiltered, truth of God's Word.
I have yet to find anyone who can prove that any of the traditions of the Catholic Church over riding any scripture.
Romans 10:
That if you confess with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved
I look forward to talking again.
Ettu.
God Bless,
