jax8686,
What I did with this question for myself is go to the Catechism of the Catholic Church (CCC) and read everything I could on eschatology (end-times stuff). I then looked at the footnotes and looked up many of the corresponding Bible passages to help me think “with the mind of the Church.”
I also read the Catechism of the Council of Trent (available from TAN Books) cover to cover (in addition to reading the CCC cover to cover). The CCC calls the Catechism of the Council of Trent a “work of first rank” (I think this is in paragraph 8 or 9 of the CCC) so don’t let modernist Catholics tell you the Catechism of the Council of Trent (also called “The Roman Catechism”) is out of date.
I also use Ludwig Ott’s “Fundamentals of Catholic Dogma” (also avail. from TAN) as a reference because Ott does a nice job of giving Scriptural references and ancient Church Father references.
I also read Carl Olson’s book (“Will Catholics be Left Behind?” from Ignatius Press) about eschatology and found that quite helpful.
Scott Hahn’s tapes on the Book of Revelation (St. Joseph Communications) are helpful too as he goes into much more than the Book of Revelation here. If you do a lot of driving these might be very nice. Steve Wood also has a very good tape series (Family Life Center and
www.dads.org) on the end times that I would highly recomend.
I would avoid the common situation of getting caught up in trying to use Scripture as a “Divining tool” though. There are many examples of individuals who do this with potential great harm to their and other peoples faith often times I’m afraid.
The “seas giving up their dead” is probably a reference to everybody getting their bodies back at the end of time (both the saved and the unsaved) - the general judgment.
