Do not they blaspheme... — To “blaspheme” is to hurt with the tongue, and includes all manner of evil speech; but a more exclusive use of the word is with regard to things divine, and particularly the unpardonable sin against the Holy Ghost (Matthew 12:31). A moment’s reflection will show, unhappily, that this is alluded to in the text.
That worthy name by the which ye are called? — Better, that good, that glorious Name which was invoiced (or, called) over you — viz., at baptism. “Into the Name of the Father, and of the Son, and of the Holy Ghost” (Matthew 28:19) had all been baptised who were thus addressed; but most probably the Second Person of the Trinity is referred to here. And it was the scorn and contempt visited upon His Name, which changed the mere abuse and ribaldry into a perilous likeness to the deadliest sin. Most commentators thus restrict the Name here to that of Christ. If their view be correct, the blasphemy would probably be linked with that epithet of “Christian” — then so dishonourable — coined, we are told, first in Antioch (Acts 11:26). But there were far more insulting terms found for the poor and struggling believer — “Nazarene,” “Atheist,” and even worse.
