We did
Both the old Baltimore Catechism series and the new Catechism are based on Scripture - for each point of Catechism teaching, there is a Scripture verse, or verses, backing it up.
Yeh === maybe one verse --- but they ignored the dozens of other scripture verses that negated what the catechism taught.
Either you weren't paying attention the first time, you have completely forgotten, or you are purposefully, willfully, and conveniently disregarding this little fact in order to justify your leaving the Church.
or I came to learn the truth and the truth set me free.
You will need to come up with another reason, because I don't buy your assertion that you just happened to discover the Church's teachings are "mere fiction and superstition."
Okay ---- the fraudulent documentation and prefabrications and magisterial hypocrisy and spiritual pretentions and the gruesome history of those Inquisitions were also quite persuasive.
You are presenting yourself as a Protestant who is ignorant of Catholic teaching, but you know that teaching very well and are CHOOSING to argue against it.
So what!
Your arguments are bogus, sir!
It must be due to all those years in catechism classes.
I ask for the third time in recent months: have you ever been in a Catholic seminary?
I understand that you're under no obligation to answer, but I ask anyway in the expectation that you will.
Free to do what? We are bound by the laws and teachings of the Church of Our Lord Jesus Christ. Of our own free will do we choose to follow Him. What are you free to do, sir? Are you free of His cross? Are you free to do what you will? What do you will?
You have admitted that each point of the Catechism is backed up by Scripture. As I said, you have knowingly and willfully left the Church and are promoting schism (Ref. John 17:11, 21, 22, 23 where Jesus prays that we all may be one). That is a mortal sin, except I guess you don't believe in mortal sin anymore, either, do you? Or as you said yourself, "so what!"
You aren't seeking the Truth, you are seeking justification for yourself by believing falsehoods. Your beliefs might also be described as "spiritually pretentious."
