The Eastern Rites administer “chrismation” at the same time as Baptism. I rationalize Confirmation in the very sense of the word, that one has studied and firmly accepts the tenets of the Catholic faith. At such a point, one should be considered a disciple of Christ and ready to show some fruits of the Holy Spirit by undertaking some mission in the Church.
The Holy Spirit came down upon Mary and Jesus’ disciples on Pentecost, the day that Jews celebrate receiving the Torah from God. They were gathered together in prayer when they were inspired by the Holy Spirit.
In the US, the sacrament is ritualized and ceremonialized and usually a bishop imparts the sacrament, but the underlying maturation of a person in the faith should be the reason for requesting the anointing of the Sacrament – all this in my opinion. Further we should be prepared thereby to profess our faith to the point of death, if need be.
So, if we’re too busy for all this, then it’s good to put it off until one is ready to make the commitment.
