“The Scripture does not say “If something is not recorded in Scripture, it is not necessary for you to know”, or “All that you need to know is in the Scripture”. Christ Himself surely made refernce to common knowledge of His time (e.g. the disaster of the Tower of Siloe, Lk 13:4) and quoted things that are not in the Christian Scripture (John 7:38; Jude quotes from Enoch, Jude 1:14).”
I simply stated that as far as I can tell, there is nothing that is not recorded in the Holy Bible that a person needs for Salvation.
“Second, you worry of the “necessary” as if there is any harm in the unnecessary.”
Harm in the unnecesary? Not really, it is just unnecessary, unneeded. Not important in regards to Salvation.
“What feeling is driving you if not spiritual sloth?”
Love of my Lord and Saviour and fellow man.
“Why are you not curious how Mary ended her days”
Why would I be? The way Christ ended His on earth are what is important.
“how Sts Peter and Paul died”
I actually did a study many years ago on how the apostles met their ends. It was very interesting, but not necessary to know for Salvation.
“how the Trinity doctrine get established”
We actually have been taught this in Protestant churches.
“what errors the Church fell into and how they were corrected?”
Not being a Catholic, I don’t really concern myself with what errors that church has made and how they were corrected. I know the big ones. I know the current one.
“Thirdly, while the scripture does not say that only the Scripture is necessary for salvation”
No, scripture only tells us what or rather WHO is needed for Salvation.
it is just unnecessary, unneeded
If I love someone, I want to know her family. I love Jesus and I want to know about His saints. Neither is "necessary"
I know the big ones. I know the current one.
Protestant communities of faith don't' know much about the Catholic Church, and what their pastors do know they lie about.
