"The Death of Stephen Disciples multiplied greatly in Jerusalem, and many of the priests were obedient to the faith. Stephen, full of faith, was doing great wonders and miracles among the people. The Jewish leaders were stirred to greater anger as they saw priests turning from their traditions, and from the sacrifices and offerings, and accepting Jesus as the great sacrifice. With power from on high, Stephen reproved the unbelieving priests and elders, and exalted Jesus before them. They could not withstand the wisdom and power with which he spoke, and as they found that they could prevail nothing against him, they hired men to swear falsely that they had heard him speak blasphemous words against Moses and against God. They stirred up the people and took Stephen, and, through false witnesses, accused him of speaking against the temple and the law. They testified that they had heard him say that this Jesus of Nazareth would destroy the customs which Moses gave them. EW 197"
"And they were not able to resist the wisdom and the spirit by which he spake."
EGW directly alludes to Acts 6:10, using similar wording to describe the inability of Stephen's opponents to resist his wisdom.
