CIC 94 Thanks to the assistance of the Holy Spirit, the understanding of both the realities and the words of the heritage of faith is able to grow in the life of the Church:
– “through the contemplation and study of believers who ponder these things in their hearts”;1 it is in particular “theological research [which] deepens knowledge of revealed truth”.2
– “from the intimate sense of spiritual realities which [believers] experience”,3 the sacred Scriptures “grow with the one who reads them.”3
– “from the preaching of those who have received, along with their right of succession in the episcopate, the sure charism of truth”.5

CIC 527 Jesus’ circumcision, on the eighth day after his birth,6 is the sign of his incorporation into Abraham’s descendants, into the people of the covenant. It is the sign of his submission to the Law7 and his deputation to Israel’s worship, in which he will participate throughout his life. This sign prefigures that “circumcision of Christ” which is Baptism.8

CIC 2599 The Son of God who became Son of the Virgin also learned to pray according to his human heart. He learns the formulas of prayer from his mother, who kept in her heart and meditated upon all the “great things” done by the Almighty.9 He learns to pray in the words and rhythms of the prayer of his people, in the synagogue at Nazareth and the Temple at Jerusalem. But his prayer springs from an otherwise secret source, as he intimates at the age of twelve: “I must be in my Father’s house.”10 Here the newness of prayer in the fullness of time begins to be revealed: his filial prayer, which the Father awaits from his children, is finally going to be lived out by the only Son in his humanity, with and for men.
