Octave Day of Saints Peter and Paul
Here is today's collect from the Sarum Missal: O God Whose right hand raised St. Peter the Apostle as he walked on the waves that he sank not, and delivered His Apostle Paul, who thrice suffered shipwreck, from the deep of the sea, graciously hear us and grant that for the sake of both we may attain unto everlasting glory.
May God strengthen you and uphold you, my friend. May He carry you through all dangers to everlasting joy.
The post-Communion prayer is also lovely to contemplate: O Lord let the Sacrament which we have received prepare for us a heavenly healing at the prayers of Thy Apostles Peter and Paul.
