The Groom and Bride are crowned (wed) to one another with these words: “Lord our God, crown them with glory and honor.”
As the above words, taken from an Orthodox wedding service indicates, some in the Orthodox Church believe it is exactly when the Priest blesses the wedding couple with the words of Psalm 8:5, “Crown them with glory and honor“, that the couple are considered united in the sacrament of marriage. An interesting commentary on Psalm 8:5 might give us insight into how Orthodoxy understands both what it is to be human and how marriage fits into the divinely instituted sacrament of marriage.
Genesis 1:27 states that humankind, male and female, is created in the divine ‘image.’ What does this mean? Certainly it cannot mean that humans bear some kind of physical resemblance to God, for in contrast to neighboring peoples who fashioned idols of their gods, Israelites were absolutely forbidden to make any physical image of Yahweh. So the idea that humans have any kind of physical likeness to God would be unimaginable to the biblical authors. Scholars still debate the precise meaning of the phrase ‘in the divine image,’ but many believe that Psalm 8:5 provides important insight. The psalm praises God for creating humanity as ‘a little lower than God, / and crowned . . . with glory and honor.’ In the Old Testament, the Hebrew word for ‘glory’ (kabod) is regularly used of Yahweh, but here it is applied to humans. Kabod or ‘glory’ refers to God’s reality or presence made visible, and the psalm indicates that God somehow shares this divine reality with humankind. …
describing humans as created in the image of God suggests that God shares something of God’s own self with the human creature. Further, humankind is created to be a visible manifestation of God on earth; this is a major purpose for human existence. … creation of humankind in the image and likeness of God above all points to ‘something happening’ between God and the human race. ‘What God has decided to create must stand in a relationship to him.’ Against this background, it becomes evident that the Priestly redactor presents a stark contrast between the religious beliefs of Israel and Babylonia. In the Babylonian creation myth, humans are created to serve the gods as slaves serve their masters. (Marielle Frigge, Beginning Biblical Studies, p 90)

When the priest blesses the wedding couple with the words, “Lord, crown them with glory and honor”, he is asking the Lord God to make His presence manifest in the couple being united in marriage and in one flesh. God is sharing His divinity with the couple newly united in marriage and they together – two in one flesh – are revealing this presence of God in humanity. It is a revelation that doesn’t occur in one human alone, but the goodness of God being revealed in the couple as couple. The couple is not created by God to serve God as God’s slaves, but to reveal God present in humanity. Matrimony is revealing “something happening between God and the human race” in a way that one person alone is not capable of revealing. Humanity is created by God to be in communion with God. The community of marriage makes this union between God and humans visible in a unique way. It reveals how God makes male and female in God’s own image – in other words as icons of God.
The two become one flesh – and this is in some mysterious way revelation of the incarnation of God.
“For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.” This mystery is a profound one, and I am saying that it refers to Christ and the church . . .” (Ephesians 5:31-32)
