Indeed - my point was merely they are easier to escape than the other cults, since they won’t try to separate you from your family, or at least haven’t been known for doing that, yet, although given how unstable they are, and the wide disparity in belief and practices between their different congregations, I should not be surprised if an individual UUA parish were to attempt it.
An Orthodox Bible should also I think be something you would find useful in this respect, in that indeed, the Byzantine Rite Catholics and Eastern Orthodox use the same Bibles. The main reason for using one of ours, namely, the Orthodox Study BIble, would be to compare the Septuagint to the Vulgate Old Testament (the Douai Rheims includes a translation of St. Jerome’s translation of the Septuagint Psalter, which lacks Psalm 151 but otherwise matches the Psalter used by the Orthodox). The differences in what is regarded as canonical are extremely minor. Now, obviously, I don’t imagine you would need to do this, but in general, I use Catholic Bibles for convenience because I desire access to this material, and I also am very happy with the Psalter in the Challoner Douai-Rheims Bible.
I also particularly like the Knox Bible (which is a Catholic Bible, no connection to John Knox, the extremely anti-Catholic and in my opinion somewhat disagreeable founder of Scottish Presbyterianism).
