(Heb 4, 2) In fact we have received the good news
[2] For in fact we have received the good news just as they did. But the word that they heard did not profit them, for they were not united in faith with those who listened.

(CCC 1100) The Word of God. The Holy Spirit first recalls the meaning of the salvation event to the liturgical assembly by giving life to the Word of God, which is proclaimed so that it may be received and lived: In the celebration of the liturgy, Sacred Scripture is extremely important. From it come the lessons that are read and explained in the homily and the psalms that are sung. It is from the Scriptures that the prayers, collects, and hymns draw their inspiration and their force, and that actions and signs derive their meaning (SC 24). (CCC 1176) The celebration of the Liturgy of the Hours demands not only harmonizing the voice with the praying heart, but also a deeper "understanding of the liturgy and of the Bible, especially of the Psalms" (SC 90). (CCC 2587) The Psalter is the book in which the Word of God becomes man's prayer. In other books of the Old Testament, "the words proclaim [God's] works and bring to light the mystery they contain" (DV 2). The words of the Psalmist, sung for God, both express and acclaim the Lord's saving works; the same Spirit inspires both God's work and man's response. Christ will unite the two. In him, the psalms continue to teach us how to pray. (CCC 1160) Christian iconography expresses in images the same Gospel message that Scripture communicates by words. Image and word illuminate each other: We declare that we preserve intact all the written and unwritten traditions of the Church which have been entrusted to us. One of these traditions consists in the production of representational artwork, which accords with the history of the preaching of the Gospel. For it confirms that the incarnation of the Word of God was real and not imaginary, and to our benefit as well, for realities that illustrate each other undoubtedly reflect each other's meaning (Council of Nicaea II (787): COD 111).
