>>239173884th Century Christians were getting openly murdered in the streets.
If they were seen praying they were murdered.
If they spoke in any way about their faith they were murdered.
If they didn't participate in the orgies they would get murdered. If they didn't get drunk they were murdered. If they didn't bow their head to the gods of rome they were murdered. Hell, many roman pagans were murdered on being suspect of being a Christian that was how authoritarian and evil 4th century romans were.
American blacks have never faced the level of prejudice that 4th century Christians face.
Pick up a history book. See how hard it was for the average black slave and compare it to the average Christian in rome during the 3rd and 4th century after the death and resurrection of Jesus Christ.
