From Dom Guéranger's The Liturgical Year.

 

On the 10th July we honoured St. Felicitas, mother of the Martyrs, giving a second and heavenly birth to her seven sons. But her own recompense was delayed for four long months. The Church has inscribed her name on the sacred diptychs; let us, then, again offer her our prayers and praises on this day, whereon the sword at length fulfilled her desires, and in justification of her name, restored her to her sons in eternal felicity.

Antiphon

Ant. Date ei de fructu manuum suarum,
et laudent eam in portis opera ejus.

V. Diffusa est gratia in labiis tuis.

℟. Propterea benedixit te Deus in seternum.
Ant. Give her of the fruit of her hands,
and let her works praise her in the gates.

V. Grace is spread abroad in thy lips.

℟. Therefore hath God blessed thee forever.

Prayer

Praesta, quaesummus omnipotens Deus; ut, beatae Felicitatis Martyris tuae solemnia recensentes, meritis ipsius protegamur et precibus. Per Dominum.
Grant we beseech thee, O Almighty God, that celebrating the solemnity of blessed Felicitas thy Martyr, e may be protected by her merits and prayers. Through our Lord.
