It seems to me that a lot of these discussions are tied to our addiction to a time line. We have to see things as happening in time. God is not bound by time. That’s a mystery that we cannot fully understand but accept by faith. I tell our son that he is sealed with the mark of the Holy Spirit through Baptism and Confirmation. This sort of drives him crazy since he is “unchurched” at the moment. But every chance I get I tell him, “God bless you.”
And it is "crazy," as the Holy Spirit distinctly states that repentance and wholehearted faith are required for baptism, (Acts 2:38; 8:36,37) and nowhere manifestly records an infant being baptized, which circumcision (Col. 2:11) only has limited correspondence to (in being a figure), while Peter testified how God purified the hearts of souls by faith, before baptism. (Acts 10:43:47; 15:7-9)
Moreover, spiritual dead clergy cannot convey the Holy Spirit, while there simply is no separate class of believers distinctively titled "priests," the distinctive word for which the Holy Spirit never uses for NT pastors. See here to save my typing again.
He apparently knows the truth, whereas you only have unwarranted fideism in a mirage. Whatever you and/or your church have done cannot grant him justification from his Sin and sins before The God. Only his irreversible commitment to the Jesus of the Bible pursuant to regeneration in the spirit by The Word of The Holy Spirit can do that.
(1 John 3:9)
See ,that is not "faith" in God, that is faith in your church
No where does the scripture tell us Baptism seals anyone with the Holy Spirit.. and there is no such thing as "confirmation " in the NT
It is our faith alone in Christ for our salvation that seals us.. your son has no "seal" if he has not trusted in Christ
And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit,(Eph1:13)
