Almighty God, who upheld your servant Irenaeus with strength to maintain the truth against every blast of vain doctrine: Keep us, we pray, steadfast in your true religion, that in constancy and peace we may walk in the way that leads to eternal life; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
