‘St John the Baptist [is] the only saint whose birth is commemorated because it marked the beginning of the fulfilment of the divine promises: John is that “prophet”, identified with Elijah, who was destined to be the immediate precursor of the Messiah, to prepare the people of Israel for his coming (cf. Matthew 11.14; 17.10-13). His Feast reminds us that our life is entirely and always “relative” to Christ and is fulfilled by accepting him, the Word, the Light and the Bridegroom, whose voices, lamps and friends we are (cf. John 1.1, 23; 1.7-8; 3.29). “He must increase, but I must decrease” (John 3.30): the Baptist’s words are a programme for every Christian’.
from his Angelus, 25 June 2006, by Pope Benedict XVI
Almighty God, by whose providence thy servant Saint John the Baptist was wonderfully born, and sent to prepare the way of thy Son our Saviour, by preaching of repentance: make us so to follow his doctrine and holy life, that we may truly repent according to his preaching; and after his example constantly speak the truth, boldly rebuke vice, and patiently suffer for the truth’s sake; through the same Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end. Amen. - Divine Worship: The Missal.
