Saint Irenaeus of Lyon

A life of faith

Irenaeus studied under Polycarp before serving the church at Lyon. He became bishop after Pothinus and defended the received Christian faith through preaching and writing. The calendar remembers his five books against heresies and his intervention in a dispute over the date of Easter. His life joins theological work with concern for communion between churches.

The Eastern Orthodox Church remembers saints in prayer and commemoration. Their lives offer examples for Christians learning to live their faith.

A reflection

Irenaeus invites reflection on pursuing theological understanding while caring for communion between Christians.
