Restorer of innocence

O God, restorer and lover of innocence, direct to yourself the hearts of your servants, that, seized by the fervor of your Spirit, they may be found both steadfast in faith and effective in work.  Through.

"O God, who delight in innocence and restore it, direct the hearts of your servants to yourself, that, caught up in the fire of your Spirit, we may be found steadfast in faith and effective in works.  Through."

"Deus, innocentiae restitutor et amator, dirige ad te tuorum corda servorum, ut, spíritus tui fervore concepto, et in fide inveniantur stabiles et in opere efficaces. Per."
