The Seven Gifts of the Holy Spirit
Wisdom is both the knowledge of and judgment about “divine things” and the ability to judge and direct human affairs according to divine truth (I/I.1.6; I/II.69.3; II/II.8.6; II/II.45.1–5).
Understanding is penetrating insight into the very heart of things, especially those higher truths that are necessary for our eternal salvation—in effect, the ability to “see” God (I/I.12.5; I/II.69.2; II/II.8.1–3).
Counsel allows a man to be directed by God in matters necessary for his salvation (II/II.52.1).
Fortitude denotes a firmness of mind in doing good and in avoiding evil, particularly when it is difficult or dangerous to do so, and the confidence to overcome all obstacles, even deadly ones, by virtue of the assurance of everlasting life (I/II.61.3; II/II.123.2; II/II.139.1).
Knowledge is the ability to judge correctly about matters of faith and right action, so as to never wander from the straight path of justice (II/II.9.3).
Piety is, principally, revering God with filial affection, paying worship and duty to God, paying due duty to all men on account of their relationship to God, and honoring the saints and not contradicting Scripture. The Latin word pietas denotes the reverence that we give to our father and to our country; since God is the Father of all, the worship of God is also called piety (I/II.68.4; II/II.121.1).
Fear of God is, in this context, “filial” or chaste fear whereby we revere God and avoid separating ourselves from him—as opposed to “servile” fear, whereby we fear punishment (I/II.67.4; II/II.19.9)
The Sacrament of Confirmation is one of the three sacraments of initiation into the Catholic Church (together with Baptism and Holy Communion).
This special anointing given by the bishop or priest has the effect of increasing, deepening, and strengthening the sanctifying grace of God given to us at our baptism; while baptism removes from our souls the stain of original sin, Confirmation pours into our souls the power of the Holy Spirit and his seven gifts – just like the Apostles received at Pentecost.
Confirmation is, therefore, the sacrament most closely identified with the special outpouring of the Holy Spirit.
Now when the apostles at Jerusalem heard that Samaria had accepted the word of God, they sent Peter and John to them. The two went down and prayed for them that they might receive the Holy Spirit (for as yet the Spirit had not come upon any of them; they had only been baptized in the name of the Lord Jesus). Then Peter and John laid their hands on them, and they received the Holy Spirit. (Acts 8:14-17)
If baptism is like a seed of Divine life in the soul, then Confirmation makes that seed come to full bloom. According to the Catechism of the Catholic Church (1303) below are the five real spiritual effects that happen to Christians through the anointing of the Sacrament of Confirmation.
