Confirmation and the Unity of the Holy Spirit

"Now when the apostles in Jerusalem heard that Samaria had received the word of God, they sent them Peter and John, who came down and prayed for them that they might receive the Holy Spirit. For He had not yet fallen upon any of them; they had simply been baptized in the name of the Lord Jesus. Then they began laying their hands on them, and they were receiving the Holy Spirit." (Acts 8:14-17)

A week ago I wrote some comments on Baptism in relation to ecclesial unity. (See here.) Today I posted some related thoughts here about Confirmation and the "unity of the Spirit". Confirmation is that sacrament that "strengthens baptismal grace" by filling and sealing us with the Holy Spirit. (CCC #1289)
