Article 2 IN THE FULLNESS OF TIME

From The Catechism of the Catholic Church

2599
The Son of God who became Son of the Virgin learned to pray in his human heart.
He learns to pray from his mother, who kept all the great things the Almighty
had done and treasured them in her heart.⁴¹ 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.”⁴² 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.
