MYSTERY OF THE HOLY SPIRIT

Definition

The sacrament of confirmation, especially in Eastern Christianity. It is called a mystery because it confers invisible grace through visible anointing. And it is the distinctive sacrament of the Holy Spirit as power according to the promise of Christ to his followers before Pentecost, that they would receive power to be his witnesses, i.e., martyrs, even to the ends of the earth.
