St. Luke the Evangelist

Almighty God, who inspired your servant Luke the physician to set forth in the Gospel the love and healing power of your Son: Graciously continue in your Church this love and power to heal, to the praise and glory of your Name; through Jesus Christ our Lord, who lives and reigns with you, in the unity of the Holy Spirit, one God, now and for ever. Amen.

From the Book of Common Prayer
