The Liturgy of Catecumens
The word liturgy means a common act. It is something that a group of people share in together, not just one person. It is not just the priest reciting prayers and people listening but all who attend participate. We pray together, we sing songs of praise together and not for ourselves, but for all. When we pray during the Divine Liturgy we always pray in the plural. You will always hear we. us. or our, but never I, me, or mine. We learned during the Liturgy of Preparation that one person may bake the prosphora and give it as an offering, but it is still a gift from all who attend and participate in the Divine Liturgy.
Blessed is the Kingdom of the Father and of the Son and of the Holy Spirit, now and ever and unto ages of ages.
This doxology (a hymn or verse of praise to God) begins every holy rite. It tells us that we should set aside our own interests and wants to glorify God, the Father, and the Son and the Holy Spirit. The three persons of God (the Trinity). Also, that we are entering God’s Kingdom.
