Equal of the Apostles and Emperor Constantine with his Mother Helen - Troparion & Kontakion

Troparion — Tone 8

Having seen the figure of the Cross in the heavens, / and like Paul not having received his call from men, O Lord, / Your apostle among rulers, the Emperor Constantine, / has been set by Your hand as ruler over the Imperial City / that he preserved in peace for many years, / through the prayers of the Theotokos, O only lover of mankind.

Kontakion — Tone 3

Today Constantine and his mother Helen / reveal the precious Cross, / the weapon of the faithful / against their enemies. / For our sakes, it has been shown to be a great sign, and fearsome in battle.
