The Divine Liturgy is the Kingdom of God

“The Divine Liturgy is the Kingdom of God, and the food at the Supper of the Kingdom is love. Through repentance and fear of God, we traverse the sea of this life and arrive at love.

‘Repentance is the ship,

fear is its helmsman and

love is the divine harbor.

So fear places us in the ship of repentance, conveys us across the sullied sea of life and brings us to the divine harbor which is love, to which all those who are weary and heavy laden attain through repentance [cf. Matt. 11:28]. Once we arrive at love, we have arrived at God.’”

(St. Isaac the Syrian in The Divine Liturgy: A Commentary in the Light of the Fathers  by Hieromonk Gregorios, p 294)
