"6:8 And Stephen, full of grace and power, was performing great wonders and signs among the people." I assume Rome does not believe Stephen was sinless from birth.
How bout Luke 7:28? I tell you, among those born of women there is no one greater than John; yet the one who is least in the kingdom of God is greater than he.”
Unfortunately, the correct translation of this verse is “full of faith (pistis) and power.” The word for grace (charis) is not found in the verse.
