Although there is no biblical formula for what we do on Sunday mornings, everything in the liturgy is absolutely a reflection and reminder of the Holy Scriptures, from the incense (a sweet aroma reminding worshippers that their “prayers arise like incense” before God), to the crossing of oneself (an invocation of the Holy Trinity).
The liturgy features the gathering of the community where the biblical recitations and acclamations along with rich creedal statements are made. The culmination of the liturgy is the Holy Eucharist, one of the highlights of the Christian life, because it is an opportunity for each faithful to call to mind and actively participate in what Christ did for us through his cross and resurrection.
The history of the liturgy begins in the Old Testament. It is centered on sacrifices laid out in Leviticus, making it a paradigm for the agenda of the Christian liturgy. We know that the celebration of the Holy Eucharist (Liturgy) can be traced to a norm in the Early Church (cf. Didaché).
Through church life we gain wisdom from those who lived before us in the line of liturgical tradition that ultimately derived from those who were taught directly by Christ and His disciples.
Tradition is a countercultural method often resisting contemporary, secular decay that seeks to penetrate Christian worship. Instead of deferring to the newest, shiniest, most popular fad, Orthodoxy heeds to ancient wisdom, uniting itself to the members of the Church who came before us while tuning out those contemporary influences, which can distort our view of God and His Church.
Liturgy is not entertainment. It is not a consumer product. It must remain theocentric. That which pleases God and puts him at the very center is considered the wisest and most Orthodox expression of worship.
