(Rev 4, 7-11) Who was, and who is, and who is to come [7] The first creature resembled a lion, the second was like a calf, the third had a face like that of a human being, and the fourth looked like an eagle in flight. [8] The four living creatures, each of them with six wings, were covered with eyes inside and out. Day and night they do not stop exclaiming: "Holy, holy, holy is the Lord God almighty, who was, and who is, and who is to come." [9] Whenever the living creatures give glory and honor and thanks to the one who sits on the throne, who lives forever and ever, [10] the twenty-four elders fall down before the one who sits on the throne and worship him, who lives forever and ever. They throw down their crowns before the throne, exclaiming: [11] "Worthy are you, Lord our God, to receive glory and honor and power, for you created all things; because of your will they came to be and were created."
(CCC 2642) The Revelation of "what must soon take place," the Apocalypse, is borne along by the songs of the heavenly liturgy (Cf. Rev 4:8-11; 5:9-14; 7:10-12) but also by the intercession of the "witnesses" (martyrs) (Rev 6:10). The prophets and the saints, all those who were slain on earth for their witness to Jesus, the vast throng of those who, having come through the great tribulation, have gone before us into the Kingdom, all sing the praise and glory of him who sits on the throne, and of the Lamb (Cf. Rev 18:24; 19:1-8). In communion with them, the Church on earth also sings these songs with faith in the midst of trial. By means of petition and intercession, faith hopes against all hope and gives thanks to the "Father of lights," from whom "every perfect gift" comes down (Jas 1:17). Thus faith is pure praise. (CCC 2855) The final doxology, "For the kingdom, the power and the glory are yours, now and forever," takes up again, by inclusion, the first three petitions to our Father: the glorification of his name, the coming of his reign, and the power of his saving will. But these prayers are now proclaimed as adoration and thanksgiving, as in the liturgy of heaven (Cf. Rev 1:6; 4:11; 5:13). The ruler of this world has mendaciously attributed to himself the three titles of kingship, power, and glory (Cf. Lk 4:5-6). Christ, the Lord, restores them to his Father and our Father, until he hands over the kingdom to him when the mystery of salvation will be brought to its completion and God will be all in all (1 Cor 15:24-28). (CCC 295) We believe that God created the world according to his wisdom (Cf. Wis 9:9). It is not the product of any necessity whatever, nor of blind fate or chance. We believe that it proceeds from God's free will; he wanted to make his creatures share in his being, wisdom and goodness: "For you created all things, and by your will they existed and were created" (Rev 4:11). Therefore the Psalmist exclaims: "O LORD, how manifold are your works! In wisdom you have made them all"; and "The LORD is good to all, and his compassion is over all that he has made" (Pss 104:24; 145:9).
