Libyan Christians

Arius (; ; 250 or 256 – 336) was a Cyrenaic presbyter and ascetic. He has been regarded as the founder of Arianism, which holds that Jesus Christ was not coeternal with God the Father, but was rather created directly by God the Father before anything else, as the true Firstborn. Arian theology and its doctrine regarding the nature of the Godhead showed a belief in radical subordinationism, a view notably disputed by 4th century figures such as Athanasius of Alexandria.

Synesius of Cyrene (; ; c. 373 – c. 414) was a Greek bishop of Ptolemais in ancient Libya, a part of the Western Pentapolis of Cyrenaica after 410. He was born of wealthy parents at Balagrae (now Bayda, Libya) near Cyrene between 370 and 375.
