O Lord, thy disciple Emperor Constantine, who saw in the sky the Sign of Thy Cross, Accepted the call that came straight from Thee, as it happened to Paul, and not from any man. He built his capital and entrusted it to Thy care. Preserve our country in everlasting peace, through the intercession of the Mother of God, for Thou art the Lover of mankind.
Today, Constantine with his mother Helen present the Cross, the most precious wood. It shames unbelievers. It is a weapon of faithful kings against their adversaries. A great sign has come forth for us which is awesome in battle.
Saint Helena, pray for us, for Great Britain and for all mothers.
Saint Constantine, pray for us and for all monarchs and rulers.
