(King of France)
OGOD, who didst call thy servant Louis to an earthly throne that he might advance thy heavenly kingdom, and didst endue him with zeal for thy Church and charity towards thy people: Mercifully grant that we who commemorate his example may be fruitful in good works, and attain to the glorious fellowship of thy saints; through Jesus Christ our Lord. Amen.
(Bishop of Hippo)
O LORD God, who art the light of the minds that know thee, the life of the souls that love thee, and the strength of the hearts that serve thee: Help us, after the example of thy servant Saint Augustine, so to know thee that we may truly love thee, so to love thee that we may fully serve thee, whom to serve is perfect, freedom; through Jesus Christ our Lord. Amen.
The Epistle. Hebrews 12:22-24, 28-29.
BUT ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels, to the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect, and to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel. Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear: for our God is a consuming fire.
The Gospel. St. John 17:1-8.
THESE words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: as thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. I have glorified thee on the earth: I have finished the work which thou gavest me to do. And now, 0 Father, glorify thou me with thine own self with the glory which I had with thee before the world was. I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word. Now they have known that all things whatsoever thou hast given me are of thee. For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me.
Beheading of St John the Baptist
Almighty God, who called thy servant John the Baptist to be the forerunner of your incarnate Son in birth and in death: strengthen us by thy grace that, as he suffered for the truth, so we to may boldly resist corruption and vice and receive with him the unfading crown of glory; through thy Son Jesus Christ our Lord, who livith and reighneth with thee in the unity of the Holy Ghost, ever one God, unto the ages of ages. Amen.
