The Council of
Nicaea confessed the divinity of the Son,
“true God of true God” and “of one Being with the Father.” But it did not
address the divinity of the Holy Spirit. A few years after the Council of
Nicaea, Macedonius, Patriarch of Constantinople, the new imperial capital,
denied the divinity of the Holy Spirit. This led to the Second Ecumenical
Council meeting in Constantinople in 381. It completed the profession of faith
of Nicaea, adding to the original text that the Holy Spirit is “Lord and giver of life, who proceeds from
the Father and is worshipped and glorified with the Father and the Son.” In
words that bear an undeniable kinship to the language of Scripture, the Creed,
following Paul (2 Cor 3:17), describes the Spirit as “Lord.” and following the Gospel of John (Jn 6:63), as "Giver of Life." The Creed
also says that the Holy Spirit "proceeds"
from the Father (Jn 15:26) and that "he spoke through the prophets" (2
Pet 1:21).
To affirm that the Spirit is Lord (Kyrios in Greek, a translation of the Hebrew term Yahweh, "the only Lord": Deut 6:4) is to say that he is God. And to affirm that he is the giver of life is to say that he has the power of the Creator. To say that he proceeds from the Father is to deny that he is a creature. The last sentence contains the clearest testimony to the divinity of the Holy Spirit: he receives the same worship and glory as the Father and the Son, worship that can only be given to God.
Although it is not easy to represent each of the persons of the adorable Trinity in human terms, since everything we say about God falls far short of who He is, it is important to make it clear that the Spirit is not an impersonal force or a divine energy, but a divine person. Only one person can mediate between persons, in this case between the Father and the Son. Christians also relate to each of the divine persons in a personal way: we are children of the Father, brothers and sisters of the Son, and friends or temples of the Spirit, for a friend is one who fills my heart with joy and changes my life.
The Holy Spirit
is the love of God poured into our hearts. It is the way God makes Himself
present in our lives: filling our hearts with joy, attuning our intelligence to
God's way of thinking, enabling us to love unconditionally, filling us with
strength to be witnesses of Jesus Christ, and sustaining our hope in the midst
of difficulties. For this reason, we address the Spirit, just as we do the
Father and the Son, in the second person: "Come,
Holy Spirit," or "Enlighten me, Holy Spirit."
Christian life is animated by a mysterious and invisible being, yet always personal. The Spirit is the living presence of Jesus after his ascension into heaven. On the day of his Ascension, Jesus had commissioned his followers: "Go and make disciples of all nations." To these weak and rude men, the Divine Spirit gave the eminent knowledge of the Gospel (Jn 14:26: "The Spirit will teach you all things") and the strength for apostolic heroism.
