Acts 6:
[8] And Stephen, full of grace and power, did great wonders and signs among the people.
Stephen was not human? A different kind of "full of grace"?
You are, of course, correct. I did not mean to exclude the human Jesus.
Now the case of St. Stephan;
Acts 6:
5
The proposal was acceptable to the whole community, so they chose Stephen, a man filled with faith and the holy Spirit, also Philip, Prochorus, Nicanor, Timon, Parmenas, and Nicholas of Antioch, a convert to Judaism.
Luke 1:
35
And the angel said to her in reply, “The holy Spirit will come upon you, and the power of the Most High will overshadow you. Therefore the child to be born will be called holy, the Son of God.
There seems to be less emphasis on the Holy Spirit in terms of Stephan; and more emphasis on the Holy Spirit and the Power of the Most High coming over Mary. I’d say it was a matter of degree.
