Occasionally the issue of different theologies among Christian churches comes up in our Wednesday morning discussions. It seems to me that it is possible to clearly understand and be able to defend Catholic theology only if the other major positions and some of the history are also understood. I ran across a 1993 EWTN This Rock Magazine James Akin article which gives the best short explanations I have read of the differences, clearly explaining Catholic beliefs in each case, and with lots of citations and scripture references. So, if it is the kind of thing that interests you, here is the link to A Tiptoe Through Tulip. It’s pretty short (if you don’t read the footnotes).
If it doesn’t interest you, ponder this:
Always be ready to give an explanation to anyone who asks you for a reason for your hope, 16 but do it with gentleness and reverence, keeping your conscience clear, so that, when you are maligned, those who defame your good conduct in Christ may themselves be put to shame. 17 For it is better to suffer for doing good, if that be the will of God, than for doing evil. 1 Peter 3:15b-17 (NABRE)
And, to quote Akin from the linked article:
It is important for Catholics to know about these subjects: First, Catholics are often attacked by Calvinists who misunderstand the Catholic position on these issues. Second, Catholics often misunderstand the teaching of their own Church on predestination. Third, in recent years there has been a large number of Calvinists who have become Catholics . By understanding Calvinism better, Catholics can help more Calvinists make the jump.
