If this is a serious, spiritual quest, there are several "responses" to Left Behind that might be good reading. It's odd to read the assertion that Catholics are dispensationalist, because they absolutely are not! As a Catholic, we believe that our works (inspired by grace) allow us to participate with Christ in the act of propitiation: Quite the opposite of dispensationalism!
I'm not sure what a MacArthur-type church is. Are they waiting for him to return to the Phillipines? I better check... lessee... the letter to the Phillipines is right after "Galatians," right? Here's to driving Satan back to the 51st parallel! If MacArthur-type churches aren't dispenationalist do they believe in General Absolution? (Corporal acts of mercy? Private intentions? Major Creeds? Kernals of hope?)
That's John MacArthur, author of many books including "The Gospel According to Jesus".
He's otherwise a fine teacher and author, although in the last two years I've stopped agreeing with him on the Lordship salvation issue.
I'm not sure you're familiar with him, so maybe this is Greek for now. (No fault of yours, btw.)
