He on whom you see the Spirit descend and remain, this is he who baptises with the Holy Spirit.
Jn.1:33
John baptised with water. Jesus baptises with the Holy Spirit. The second baptism "confirms" the first.
In today's Gospel we have it from the highest authority, God the Father, that Baptism with the Holy Spirit is a thing and a desirable thing at that.
As Cardinal Cantalamessa says, "Baptism in the Spirit makes real and revitalises our baptism." This is certainly my experience. And, it's a constant revitalisation, not a one-off like my water baptism. Baptism by water cleansed me of original sin. Ongoing baptism in the spirit helps me stay that way.
Thank you Jesus for your gift of "baptism with the Holy Spirit and with fire" (Mt.3:11).
