[Homilies and Spiritual Instruction]
But why did the Holy Ghost come to them, not while Christ was present, nor even immediately after his departure, but, whereas Christ ascended on the fortieth day, the Spirit descended when the day of Pentecost, that is, the fiftieth, was fully come (Act. 2:1)? And how was it, if the Spirit had not yet come, that He said, Receive ye the Holy Ghost (Jn. 20:22)? In order to render them capable and meet for the reception of Him.
