Some say that by breathing He did not give them the Spirit, but made them meet to receive the Spirit. For if Daniel’s senses were so overpowered by the sight of the Angel, how would they have been overwhelmed in receiving that unutterable gift, if He had not first prepared them for it! It would not be wrong however to say that they received then the gift of a certain spiritual power, not to raise the dead and do miracles, but to remit sins: Whosesoever sins ye remit, they are remitted unto them, and whosesoever sins ye retain, they are retained.
