“When Christ comes into us, he does not sanctify our soul alone but our whole being. For by Holy Communion, ‘Body [is mingled] with body, Blood with blood…What great mysteries are these! What a miracle, that the mind of Christ should become one with our mind, that His will should be amalgamated with our will, His Body with our body, His Blood with our blood! What is our mind like when the divine mind prevails over it; what is our will like when the divine will predominates; and what becomes of the dust [our body] once the fire [of the Godhead] overcomes it!’ (St. Nicholas Cabasilas). The distribution of the pure Mysteries ‘makes those who partake worthily to be similar – by grace and by participation – to Him who is the causal Good’ (St Maximus the Confessor).
. . . St. Symeon the New Theologian extols the Lord after Holy Communion:
‘What is this measureless compassion of Yours, O Savior?
How have You accounted me worthy to become one of Your members
– I who am impure, a prodigal, a harlot?
How have You dressed me in a garment most bright,
glistering with the radiance of immortality
and making all my members into light?
For your Body, pure and divine,
is wholly radiant, wholly intermixed
and commingled ineffably with the fire of Your Divinity…
I have been united, I know, also with Your Divinity
and have become Your most pure Body,
a member shining forth, a member truly holy,
a member glittering from afar, and radiant, and shining.'”
(Hireomonk Gregorious, The Divine Liturgy, p. 297-298)
