Are you born again?
I’m confirmed. That is the sacrament where I received the Holy Spirit and made my adult-level commitment to faith (as opposed to baptism, where I was just an infant). It comes from the Bible (Acts), where the Spirit comes on the disciples and they now have what it takes to go forth and spread the Good News.
That’s not exactly what Protestants have in mind, I think, when they are born again, in that it seems like the Holy Spirit connects with them under individual, private circumstances, and they make a personal commitment to Christ. But it is similarly a gift of the presence of the Holy Spirit, to which the person responds with a commitment to a life converted to Christ.
Not to say that some don’t just slide through the confirmation program without thinking about it, but then some people who are born again backslide, too. (Wasn’t Larry Flynt born again back in the 80s? Bob Dylan?)
