This past Sunday (June 24) was the feast of the Nativity of St. John the Baptist. It is one of only three births that we celebrate in the liturgical calendar (the other two being the birth of Our Lord at Christmas and the birth of Our Lady on Sept 8). This is because St. John the Baptist was one of a very small handful of human beings to be born without the stain of original sin. In other words, he was a saint even in his birth. Hence, the Church celebrates his birth as the great feast in his honor (even greater than the feast of his martyrdom in August).
Ant. The Lord has called me by my name from my mother's womb, and He has made my mouth like a sharp sword; He has protected me under the shadow of His hand, and He has made me as a chosen arrow.
V. It is good to give praise to the Lord, and to sing to Thy name, O Most High.
V. Glory be...
Ant. The just shall flourish like the palm tree; he shall grow up as a cedar in Lebanon.
Ant. You, child, shall be called the prophet of the Most High, for you shall go before the face of the Lord to prepare His ways.
