What religion, tradition, or denomination did the figures in the Bible practice?

Mormonism Just saying. lol

Of course they were.

The best part is that Mormons can point to the Melchizedek priesthood to prove that they practice the same religion as the patriarchs.

Seriously though, every group wants to claim that they practice the same religion as the earliest people linked to God, but that isn't how it works.
