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."
Confirmation is the sacrament whereby God completes the graces of a person’s baptism and deepens His seal within them, marking them as belonging to Him (2 Corinthians 1:22, Ephesians 1:13-14). When received within a life of faith, the outpouring of the Holy Spirit through confirmation empowers us to live the Christian life, which we simply couldn’t do otherwise. Thus, it is not a person’s “adult choice to be Catholic,” rather it is God who chooses us, and we can then choose Him day by day.
Confirmation this year is April ?, 2020.
