For I long to see you, that I may impart unto you some spiritual gift, to the end ye may be established. Bengel, taking χάρισμα as the special gift of the Holy Ghost consequent on apostolic laying on of hands (cf.
Acts 8:17, Acts 8:18), argues from this verse that neither St. Peter nor any other apostle could have been at Rome so far. Though his conclusion is probably true, it does not follow from his premiss; for τὶ χάρισμα πνευματικὸν evidently means generally any gift of grace.
All St. Paul implies is that he hopes to do them some spiritual good, so as to settle and strengthen them; and in the next verse, with characteristic delicacy, he even modifies what he has said, so as to guard against being supposed to imply that the benefit would be all on their side.
