REQUIREMENTS FOR RECEIVING THE HOLY SPIRIT

"Receive the Holy Spirit", the Lord said to the Apostles on the evening of the Resurrection, accompanying these words with an expressive gesture: "he breathed" on them (cf. Jn 20: 22). In this way he showed that he was communicating his Spirit to them, the Spirit of the Father and of the Son. Now, dear brothers and sisters, in today's Solemnity Scripture tells us once again how the community should be, how we should be in order to receive the gift of the Holy Spirit. In the account which describes the event of Pentecost, the sacred Author recalls that the disciples "were all together in one place". This "place" was the Cenacle, the "Upper Room" where Jesus had eaten the Last Supper with his Apostles, where he had appeared to them risen; that room which had become, so to speak, the "headquarters" of the nascent Church (cf. Acts 1: 13). The Acts of the Apostles, however, rather than insisting on the physical place, intend to point out the inner attitude of the disciples: "All these with one accord devoted themselves to prayer" (Acts 1: 14). Harmony among the disciples is thus the condition for the coming of the Holy Spirit; and a presupposition of harmony is prayer.
