On Pentecost Sunday, 2008, Pope Benedict told the gathered crowds "Today I would like to extend the invitation to all: let us rediscover, dear brothers and sisters, the beauty of being baptized in the Holy Spirit..." (Read the whole thing. Who says Catholicism isn't pentecostal at its Heart?)
Here, papal preacher Fr. Raniero Cantalamessa, OFMCap gives an amazing teaching on the baptism in the Holy Spirit as it relates to water baptism and the call to Christian maturity that baptism is. A snippet:
Here, then, is what I feel is the significance of the Baptism in the Spirit. It is God's answer to this malfunctioning that has grown up in the Christian life in the Sacrament of Baptism.
It is an accepted fact that over the last few years there has been some concern on the part of the Church, among the bishops, that the Christian sacraments, especially baptism, are being administered to people who will not make any use of them in life. As a result, it has even been suggested that baptism should not be administered unless there are some minimum guarantees that it will be cultivated and valued by the child in question. For one should not throw pearls to dogs, as Jesus said, and baptism is a pearl, because it is the fruit of the blood of Christ.
But it seems that God was concerned about this situation even before the Church was, and raised up here and there in the Church movements aimed at renewing Christian initiation in adults. The Charismatic Renewal is one of these movements and in it the principle grace is, without doubt, linked to the Baptism of the Spirit and to what comes before it.
It's effectiveness in reactivating baptism consists in this: finally man contributes his part -- namely, he makes a choice of faith, prepared in repentance that allows the work of God to set itself free and to emanate all its strength. It is as if the plug is pulled and the light is switched on. The gift of God is finally "untied" and the Spirit is allowed to flow like a fragrance in the Christian life.
In addition to the renewal of the grace of baptism, the Baptism in the Spirit is also a confirmation of one's own baptism, a deliberate "yes" to it, to its fruit and its commitments, and as such it is also similar to Confirmation too. Confirmation being the sacrament that develops, confirms, and brings to completion the work of baptism. From it, too, comes that desire for greater involvement in the apostolic and missionary dimension of the Church that is usually noted in those who receive the Baptism in the Spirit. They feel more inclined to cooperate with the building up of the Church, to put themselves at her service in various ministries both clerical and lay, to witness for Christ -- to do all those things that recall the happening of Pentecost and which are actuated in the Sacrament of Confirmation.
I have never read another human being describe so vividly my own experience!
The baptism in the Holy Spirit unleashed in the modern age has most certainly been a movement of God's desire for unity among His people. My heart shouts with Fr. Cantalamessa: "We men, and in particular we men of the Church, tend to limit God in His freedom: we tend to insist that He follows a compulsory pattern (the so called channels of grace) and we forget that God is a torrent that breaks loose and creates its own path and that the Spirit blows where and how he wants (notwithstanding the role of the teaching of the Church to discern what actually comes from the Spirit and what does not come from Him). What does the Baptism of the Spirit consist of and how does it work? In the Baptism of the Spirit there is a secret, mysterious move of God that is His way of becoming present, in a way that is different for each one because only He knows us in our inner part and how to act upon our unique personality."
