Saint Irenæus, Bishop of Lyons and Doctor

Almighty God, who of old through thy servant Irenæus didst hand on the faith and extend thy Church; Keep it true to the apostolical tradition and fervent to win new peoples for thee; through Jesus Christ our Lord. Amen.

¶ Or this:

Almighty God, who didst uphold thy servant Irenæus with strength to maintain the truth against every blast of vain doctrine: Keep us, we beseech thee, steadfast in thy true religion, that in constancy and peace we may walk in the way that leadeth to eternal life; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, now and for ever. Amen.

¶ Or this:

O God, who hast enlightened thy Church by the teaching of thy servant Saint Irenæus: Enrich it evermore, we beseech thee, with thy heavenly grace, and raise up faithful witnesses, who by their life and doctrine may set forth to all men the truth of thy salvation; through Jesus Christ our Lord. Amen.
