We have been in the endtimes since Christ’s Ascension.
Catholics compiled the Bible. Of course we study it.
We do not follow Protestant flavor du jour as far as the pre and post mil arguments.
That is strictly your preoccupation.
:) If I were you, I would go to your Bible and just start reading. Jeremiah, Ezekiel, Revelation.
The son of man complied the Bible into human letters, which is the word of God- and the Holy Spirit is the way we interpret the Bible.
There is no Catholic- in the Bible. Catholic is a religion- much the same as Muslim or Hindu or Shinto.
If you are a believer and lover of Jesus- then go and read and see.
