O God, who vouchsafest unto us
to keep the heavenly birthday of blessed Placidus and his companions,
thy holy Martyrs:
grant, we beseech thee;
that we may rejoice in the perpetual felicity
of their fellowship in heaven.
Through our Lord Jesus Christ, Your Son, who being God,
lives and reigns with You in the unity of the Holy Spirit,
for ever and ever.
Amen.
