Did you not know that I must be in my Father’s house
Holy Gospel of Jesus Christ according to Saint Luke 02/41-52/:”Every year his parents went to Jerusalem for the festival of the Passover. And when he was twelve years old, they went up as usual for the festival. When the festival was ended and they started to return, the boy Jesus stayed behind in Jerusalem, but his parents did not know it. Assuming that he was in the group of travellers, they went a day’s journey. Then they started to look for him among their relatives and friends. When they did not find him, they returned to Jerusalem to search for him. After three days they found him in the temple, sitting among the teachers, listening to them and asking them questions. And all who heard him were amazed at his understanding and his answers. When his parents saw him they were astonished; and his mother said to him, ‘Child, why have you treated us like this? Look, your father and I have been searching for you in great anxiety.’ He said to them, ‘Why were you searching for me? Did you not know that I must be in my Father’s house?’ But they did not understand what he said to them. Then he went down with them and came to Nazareth, and was obedient to them. His mother treasured all these things in her heart. And Jesus increased in wisdom and in years, and in divine and human favour.”
You are a priest for ever, according to the order of Melchizedek.
Letter to the Hebrews 07/11-19/:”If perfection had been attainable through the levitical priesthood for the people received the law under this priesthood what further need would there have been to speak of another priest arising according to the order of Melchizedek, rather than one according to the order of Aaron? For when there is a change in the priesthood, there is necessarily a change in the law as well. Now the one of whom these things are spoken belonged to another tribe, from which no one has ever served at the altar. For it is evident that our Lord was descended from Judah, and in connection with that tribe Moses said nothing about priests. It is even more obvious when another priest arises, resembling Melchizedek, one who has become a priest, not through a legal requirement concerning physical descent, but through the power of an indestructible life. For it is attested of him, ‘You are a priest for ever, according to the order of Melchizedek.’ There is, on the one hand, the abrogation of an earlier commandment because it was weak and ineffectual (for the law made nothing perfect); there is, on the other hand, the introduction of a better hope, through which we approach God.”
