The following is a prayer by St. Gregory of Palamas (1296-1359) for priests. I am going to be striving to include it in my daily prayers. Our leaders need our prayers as much as anyone could possibly need them.
O Lord Jesus Christ, enkindle the hearts of all thy priests with the fire of zealous love for Thee, that they may ever seek Thy glory; Give them strength that they may labor unceasingly in Thine earthly vineyard for the salvation of our souls and the glory of Thine All-Honorable and Majestic Name: of the Father, and of the Son, and of the Holy Spirit: now and ever, and unto ages of ages. Amen.
