Acts 8:14 - Coke's Commentary on the Holy Bible

They sent unto them Peter and John:— John was one of the two who were for calling down fire from heaven upon the Samaritans when they refused to entertain Christ. To sucha length did his zeal then carry him; but it was a zeal without knowledge. After the Spirit was poured out upon him, however, his mind was enlarged, and his zeal guided by knowledge and charity; then he makes no scruple of going to the Samaritans, imparting to them the gift of the Holy Spirit, and acknowledging them for Christian brethren, whom his Jewish zeal would have burnt up and destroyed. As the apostles sent Peter along with John, and he went accordingly at their appointment, it is plain that neither he nor they had any notion of the supremacy of that apostle.
