I will take some quotes, out of context here, and answer them in order.

I hope you don’t mind I took the liberty of correcting spelling.
I am assuming you mean the Canon of Scripture. Yes, it is said that Christ will come again. However, Jesus also says in Scripture - “And behold, for I am with you until the end of the age.”
That’s the whole sweet mystery of it. Jesus is physically, Body and Blood, Present in the Catholic Church. Yet the Parousia is yet to come…
maybe, with further Catechesis (as I have often found the case to be), I will one day find myself able to explain it clearly and succinctly. maybe.
For now, I have been blessed with the grace of faith.
The great thing about the Catholic Church is that we have
two sources which are entirely complementary. Both should be considered and studied at great depths, in connection with one another, if one desires to truly understand one’s Catholic Faith.
These sources are Sacred Scripture and Sacred Tradition.
That your parents did not encourage you to read Scripture is tragic, IMO, because I believe that is a parent’s job. Priests and nuns should do the same if they are relating to a child in an educational setting.
Yet the failings of its individual members is not the fault of the Church; it is the fault of sin and the human individual’s habbit of it.
Purgatory, mortal sin and venial sin are all
implied in Scripture; they are
explicitly revealed through Tradition.
