>>24461488 (OP)The Ignatius Study Bible is bigger than it seems online, it's a big giant tome. I'd recommend a smaller Catholic Bible.
The Orthodox Study Bible is much more portable, but the pages are tissue thin.
This is a common issue with study Bibles in general. They need to contain the entire text of the Bible and the commentary they use. Truth be told I'd recommend getting a Bible without commentary and then getting a supplemental commentary in another volume.
Some people seem to be interpreting the question as "should I become Catholic or Orthodox," and if that is a dilemma you're facing, I'll say that either Bible is acceptable to both churches. The Catholic and Orthodox position on the Bible is similar, they interpret most of it the same or somewhat similarly, and neither Bible will go over the schism or the disputes between the churches. I've known plenty of Catholics who use the Orthodox Study Bible. I don't know many Orthodox, so if they have some objection to the Ignatius Study Bible, I don't know it. But honestly, I doubt they'd have much of an issue with it.
