A Dictionary of All Religions and Religious Denominations/Bogomiles

BOGOMILES, a sect in the twelfth century, which sprung from the Massalians. They derived their name from the divine mercy, which its members are said to have incessantly implored; for the word bogomiles, in the Mysian tongue, signifies calling for mercy from above.

Basilius, a monk at Constantinople, was their founder, and the doctrines he taught, it is said, were similar to those of the Manicheans.
