The Book of Revelation, drawing upon depictions from the Old Testament and intertestamental literature, presents scenes of worship in Heaven. In Jewish and Christian theology, worship on earth is held to be linked mystically to worship in Heaven, to partake of it. Saint Paul taught that angels are present (invisibly) during Christian worship on earth.
Christian worship in churches with traditional, formal liturgies involves various elements found in these scenes and developed from the sacrificial system of the Mosaic Torah. Priests, servers, and choirs are dressed in white garments. Incense is used. Praises are offered to God. The Eucharist is a sacrifice. Some churches include pictures or statues of angels, usually in positions of adoration, in imitation of the worship offered by angels in heaven. Commonly, candles and lamps are found, an echo of the Menorah.
The majesty, formality, and transcendent nature of these rituals helps worshippers to focus on Almighty God and forget, for a space, the busy-ness and distractions of this earthly life. Not only is it right to offer God thanks and praise, but it is also beneficial for humans to find a time, however long or brief, on a weekly basis in which to recuperate.
John the Revelator beheld Jesus as the Lamb that was slain. John the Baptist referred to Him as the Lamb of God who takes away the sins of the world (Agnus Dei qui tollit peccata mundi). Christ is the Passover Lamb, by whose blood mankind is redeemed, and through whose benevolence mankind is liberated from Satanic oppression and death.
In Revelation, this Lamb opens the seals. He judges the world and claims it for His own. Formal liturgy, focussing on the sacrifice of Jesus, is also a space for remembering that He is God and King. The praises sung to Him by choir and congregation are an acknowledgement of His majesty.
Glory is given to Him by offering Him the best. Humans are to strive to honour Him by righteous living, confessing our sins and doing good to others out of love and gratitude. Gold and fine cloth are used, because Christ is worthy. Objects and people are consecrated to Him, because He should be at the centre of our lives; our lives should be given over to Him.
Kneeling in the presence of the King is a means of acknowledging who He is and what He has done for us. Proclaiming the Scriptures to be the word of the Lord affirms our commitment to truth in a world of crookedness and deception. The sign of the cross is a reminder of His suffering and redeeming power.
It is good to have such thoughtful and intense focus on God. It is good to worship Him with both body and soul. It is right to receive revelation from God through His Scriptures. In this world of distractions, humans need to enter the courts of the King.
How amiable are thy tabernacles, O LORD of hosts! My soul longeth, yea, even fainteth for the courts of the LORD: my heart and my flesh crieth out for the living God. Yea, the sparrow hath found an house, and the swallow a nest for herself, where she may lay her young, even thine altars, O LORD of hosts, my King, and my God. Blessed are they that dwell in thy house: they will be still praising thee. Selah. Blessed is the man whose strength is in thee; in whose heart are the ways of them. Who passing through the valley of Baca make it a well; the rain also filleth the pools. They go from strength to strength, every one of them in Zion appeareth before God. O LORD God of hosts, hear my prayer: give ear, O God of Jacob. Selah. Behold, O God our shield, and look upon the face of thine anointed. For a day in thy courts is better than a thousand. I had rather be a doorkeeper in the house of my God, than to dwell in the tents of wickedness. For the LORD God is a sun and shield: the LORD will give grace and glory: no good thing will he withhold from them that walk uprightly. O LORD of hosts, blessed is the man that trusteth in thee.
