基里尔出生于贵族家庭，是亚力山大牧首德奥斐洛的近亲，在德奥斐洛去世后，基里尔被按立为牧首。在有生之年，基里尔领导了三次艰苦的斗争：即同诺瓦蒂安异端、聂斯脱利异端以及同亚力山大的犹太人展开的斗争。诺瓦蒂安派异端起源于罗马，是长老诺瓦蒂安发起并领导的。他们以自己的美德而骄傲、身穿白色的衣服上街，禁止第二次婚姻，并主张：犯有杀人罪恶的人不能进行祷告；那些一度远离教会的人也不能重新返回教会，即使他们进行了深刻的忏悔。基里尔击败了他们，并将他们同他们的主教一同逐出亚力山大。同犹太人进行的斗争更为激烈和残酷。自从亚历山大大帝建立亚力山大城以来，犹太人在城市中非常强大。他们对基督徒的仇恨是邪恶的、疯狂的。他们进行谋反、下毒和将基督徒钉死在十字架上。在经过一段艰苦的斗争之后，基里尔同皇帝德奥多西二世一起成功地将犹太人驱逐出亚力山大。基里尔同君士坦丁堡牧首聂斯脱利的斗争在第三次普世大公会议（公元431年，艾弗所）上得到了解决。基里尔本人主持了这次会议，与此同时应罗马教宗切雷斯丁的要求代表他出席这次会议，因为当时的罗马教宗已经年迈，不能参加会议。会议上，聂斯脱利遭到了谴责和诅咒，被皇帝流放到帝国的东方边境地带。聂斯脱利遭受了可怕的死亡：他的舌头被蠕虫蚕食，正是他用这副舌头亵渎了诞神女－圣母，称她为基督的诞生者。在这场斗争结束后，基里尔得以平安地生活，并热心牧羊基督的羊群。基里尔于公元444年得以安息。据说是基里尔创作了以下的祷告词：“庆哉！童贞诞神女，满圣宠者玛利亚！”
