Thanks to Fr Christopher Phillips for this prayer posted today:
…and not just generally, but pray specifically for particular priests by name. Here’s a brief prayer to help you:
O Lord Jesus Christ, great High Priest and gracious Shepherd; bless thy servant N., whom thou hast consecrated to minister unto thee in holy things; and grant him such purity of heart and life, and such zeal for souls, that he may bring many into union with thee, and fulfill his ministry in holiness to thy glory, our Lord and Saviour; who livest and reignest in the unity of the Father and the Holy Ghost ever, one God, world without end. Amen.
