Confirmation

Made Soldier of Christ…Putting on the Whole Armor of God

“….. the reception of the sacrament of Confirmation is necessary for the completion of baptismal grace. For by the sacrament of Confirmation, [the baptized] are more perfectly bound to the Church and are enriched with a special strength of the Holy Spirit. Hence they are, as true witnesses of Christ, more strictly obliged to spread and defend the faith by word and deed. – CCC 1285

You must wear all the weapons in God's armoury, if you would find strength to resist the cunning of the devil.
Ephesians 6:11
