REMEMBER thy servant, O Lord, according to the favour which thou bearest unto thy people, and grant that, increasing in knowledge and love of thee, he may go from strength to strength, in the life of perfect service, in thy heavenly kingdom; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Ghost, ever, one God, world without end. Amen.BCP 1928
