Saint Irenaeus insists that God the Father is Creator of all, and Lord of all that exists, and of all people – the Jews, the Gentiles, and the faithful. To the Jews He is Lord and Lawgiver and to the Gentiles He is Creator and Almighty. However, “to the faithful He is as Father” since in these last times He has adopted us as sons. For all of us, though, He is Nourisher and King and Judge. [8]

Our world is encompassed by seven heavens which derive from the seven forms of service noted by the prophet Isaiah (11:2-3).

Hence, the first heaven, from the top, which includes the others, is [that] of wisdom; and the second, after it, [that] of understanding; and the third, [that] of counsel; and the fourth, counting from the top, [that] of might; the fifth [that] of knowledge; the sixth [that] of piety; and the seventh, this firmament of ours, [is] full of the fear of this Spirit who illuminates the heavens. From this pattern Moses received the seven-branched candlestick which continually shines in the sanctuary; since he received the service as a pattern of heaven, as the Word says to him, “You shall make everything after the pattern , which you have seen on the mountain”. [9]

This God is glorified by His Word and His Spirit, and by their powers who are called Cherubim and Seraphim, so that “everything, whatsoever that is in the heavenly realm, gives glory to God the Father of all.” [10]

Quotes from Saint Irenaeus of Lyon, On the Apostolic Preaching.

There is of course much that could profitably be unpacked and discussed here, but time precludes that. Suffice it to note the relationship between heaven – and heavenly powers, and all the symbolism that that entails – and worship. The Liturgy is an ascent to the Kingdom of heaven, and it is also something that includes the whole cosmos.
