He calls Abraham his father and the father of all who were in the Sanhedrin. Therefore he honors Abraham as well.
In speaking of God’s appearance to Abraham, he defines God’s living and providential relation to the whole Jewish people in the person of the forefather.
Thus by this also he overthrows the slander that he blasphemed God. By the detailed account of events dear to the Jews, St. Stephen evidently wished to calm his listeners.
At the same time he wished to ground historically his answer concerning the substance of his evangelical preaching.
This answer was expressed in parts, in various conclusions from history, and in a special presentation of the prophetic and typological predictions concerning Christ the Savior, His teaching, His sufferings, and His glory.
“Observe,” says blessed Theophylact, “how he draws their thought away from the sensible, beginning with locality, since the discussion concerned a place.
If God is the God of glory, then He does not need to receive glory from you through your temple. He Himself is the source of every glory and every good.”
