* The poetic work ''Banquet'' (''Thalia'') by the Libyan-born Egyptian Christian priest [[Arius]], age 73, expresses the doctrine that [[Jesus|Jesus of Nazareth]] was not of the same substance as [[God]] but rather had a finite nature. As an [[ascetic]], he leads a Christian community near [[Alexandria]], and comes under suspicion of [[heresy]]. Arius writes to his former schoolmate [[Eusebius of Nicomedia|Eusebius]], bishop of [[Nicomedia]], asking for support. Eusebius writes to other [[bishop]]s, and when Arius is condemned in [[September]], Eusebius gives him safe haven, and sponsors a [[synod]] at [[Bithynia]] in [[October]], which nullifies Arius's [[excommunication]] (see [[First Council of Nicaea|Council of Nicaea]]).
