"In the portrayal of Christ's Martyr Stephen - as one "full of grace and power" (vs. 6:8) as one who speaks with 'wisdom and the Spirit' (vs. 6:10) - the Martyr directs our gaze into the heavens to behold "the glory of God, and Jesus standing at the right hand of God" (vs. 7:55). Of course, it is the Lord Who is being revealed through the person of His Holy Martyr Stephen."
"Just as true icons always disclose the connection between their particular subjects and the Divine Incarnation, so likewise St. Luke's account of Christ's first Martyr, Stephen, manifests the Lord incarnate in His Church. Therefore, let the reader perceive, in the account of St. Stephen's witness, a faithful revelation of the Lord of grace and power, of wisdom and the Spirit, and of eternal Glory at the right hand of the Father."
"St. Stephen is the Proto-martyr not only in the sense of being the first martyr for the Lord, but also as the proto-type of Christ's martyrs, for all Christ's true martyrs reveal the Lord Jesus acting and teaching through His Body, the Church."
Troparion in tone 4 for St. Stephen--
O Protomartyr and mighty warrior of Christ our God,
You are victorious in battle and crowned with glory, O holy Stephen!
You confounded the council of your persecutors,
Beholding your Savior enthroned at the right hand of the Father.
Never cease to intercede for the salvation of our souls!
