Abstract
The author comments an article of the Creed ?I believe in the Holy Spirit, the Lord, the giver of life? on the basis of theological reflexion of St. Thomas of Aquinas.
He comes out from the Aquinas? sermon on this topic cultivating it further through presentation of Thomas? thoughts in Summa Theologiae, where an analysis of traditional titles of the Third Person of the Trinity is dealt with: Holy Spirit, Charity and Gift. The last part of the contribution deals in a special way with the topic of Holy Spirit the Gift and develops it in the light of Summa contra Gentiles where St.
Thomas speaks about a friendship between God and man which he attributes to the acting of Holy Spirit.
