Jas 3, 9-12 From the mouth come blessing and cursing

(Jas 3, 9-12) From the mouth come blessing and cursing
[9] With it we bless the Lord and Father, and with it we curse human beings who are made in the likeness of God. [10] From the same mouth come blessing and cursing. This need not be so, my brothers. [11] Does a spring gush forth from the same opening both pure and brackish water? [12] Can a fig tree, my brothers, produce olives, or a grapevine figs? Neither can salt water yield fresh.

(CCC 2626) Blessing expresses the basic movement of Christian prayer: it is an encounter between God and man. In blessing, God's gift and man's acceptance of it are united in dialogue with each other. The prayer of blessing is man's response to God's gifts: because God blesses, the human heart can in return bless the One who is the source of every blessing. (CCC 2627) Two fundamental forms express this movement: our prayer ascends in the Holy Spirit through Christ to the Father - we bless him for having blessed us (Cf. Eph 1:3-14; 2 Cor 1:3 7; 1 Pet 1:3-9); it implores the grace of the Holy Spirit that descends through Christ from the Father - he blesses us (Cf. 2 Cor 13:14; Rom 15:5-6, 13; Eph 6:23-24). (CCC 2663) In the living tradition of prayer, each Church proposes to its faithful, according to its historic, social, and cultural context, a language for prayer: words, melodies, gestures, iconography. The Magisterium of the Church (Cf. DV 10) has the task of discerning the fidelity of these ways of praying to the tradition of apostolic faith; it is for pastors and catechists to explain their meaning, always in relation to Jesus Christ.
