SS. Basilides, Cyrinus, Nabor and Nazarius, Martyrs
These saints, Roman soldiers, noble by birth and illustrious by their virtues, became Christians under Diocletian. Arrested and cast into prison, they were condemned to death and beheaded. Their bodies were thrown to the wild beasts who respected them; they were buried with honour by the Christians.
Intret in conspectu tuo, Domine, gemitus compeditorum: redde vicinis nostris septuplum in sinu eorum: vindica sanguinem sanctorum tuorum, qui effusus est. * Deus, venerunt gentes in haereditatem tuam: polluerunt templum sanctum tuum: posuerunt Jerusalem in pomorum custodiam.
Let the sighing of the prisoners come in before Thee, O Lord; render to our neighbours sevenfold in their bosom; revenge the blood of Thy saints, which hath been shed. * O God, the heathens are come into Thy inheritance: they have defiled Thy holy temple: they have made Jerusalem as a place to keep fruit.
(Psalm 78:11-12,1 from the Introit of Mass)
Sanctorum Martyrum tuorum Basilidis, Cyrini, Naboris atque Nazarii, quaesumus, Domine, natalitia nobis votiva resplendeant: et, quod illis contulit excellentia sempiterna, fructibus nostrae devotionis accrescat.
O Lord, may the keeping of this festival of the heavenly birthday of Thy holy martyrs, Basilides, Cyrinus, Nabor and Nazarius, shed brightness on our lives; and may the eternal glory granted them, be increased by the devout service we pay Thee.
