Mt 2, 3-11 King Herod was greatly troubled

(Mt 2, 3-11) King Herod was greatly troubled
[3] When King Herod heard this, he was greatly troubled, and all Jerusalem with him. [4] Assembling all the chief priests and the scribes of the people, he inquired of them where the Messiah was to be born. [5] They said to him, "In Bethlehem of Judea, for thus it has been written through the prophet: [6] 'And you, Bethlehem, land of Judah, are by no means least among the rulers of Judah; since from you shall come a ruler, who is to shepherd my people Israel.'" [7] Then Herod called the magi secretly and ascertained from them the time of the star's appearance. [8] He sent them to Bethlehem and said, "Go and search diligently for the child. When you have found him, bring me word, that I too may go and do him homage." [9] After their audience with the king they set out. And behold, the star that they had seen at its rising preceded them, until it came and stopped over the place where the child was. [10] They were overjoyed at seeing the star, [11] and on entering the house they saw the child with Mary his mother. They prostrated themselves and did him homage. Then they opened their treasures and offered him gifts of gold, frankincense, and myrrh.

(CCC 306) God is the sovereign master of his plan. But to carry it out he also makes use of his creatures' co-operation. This use is not a sign of weakness, but rather a token of almighty God's greatness and goodness. For God grants his creatures not only their existence, but also the dignity of acting on their own, of being causes and principles for each other, and thus of co-operating in the accomplishment of his plan. (CCC 307) To human beings God even gives the power of freely sharing in his providence by entrusting them with the responsibility of "subduing" the earth and having dominion over it (Cf. Gen 1:26-28). God thus enables men to be intelligent and free causes in order to complete the work of creation, to perfect its harmony for their own good and that of their neighbors. Though often unconscious collaborators with God's will, they can also enter deliberately into the divine plan by their actions, their prayers and their sufferings (Cf. Col 1:24). They then fully become "God's fellow workers" and co-workers for his kingdom (I Cor 3:9; I Thess 3:2; Col 4:11). (CCC 308) The truth that God is at work in all the actions of his creatures is inseparable from faith in God the Creator. God is the first cause who operates in and through secondary causes: "For God is at work in you, both to will and to work for his good pleasure” (Phil 2:13; cf. I Cor 12:6). Far from diminishing the creature's dignity, this truth enhances it. Drawn from nothingness by God's power, wisdom and goodness, it can do nothing if it is cut off from its origin, for "without a Creator the creature vanishes" (GS 36 § 3). Still less can a creature attain its ultimate end without the help of God's grace (Cf. Mt 19:26; Jn 15:5; 14:13). (CCC 309) If God the Father almighty, the Creator of the ordered and good world, cares for all his creatures, why does evil exist? To this question, as pressing as it is unavoidable and as painful as it is mysterious, no quick answer will suffice. Only Christian faith as a whole constitutes the answer to this question: the goodness of creation, the drama of sin and the patient love of God who comes to meet man by his covenants, the redemptive Incarnation of his Son, his gift of the Spirit, his gathering of the Church, the power of the sacraments and his call to a blessed life to which free creatures are invited to consent in advance, but from which, by a terrible mystery, they can also turn away in advance. There is not a single aspect of the Christian message that is not in part an answer to the question of evil.
