Augustine of Hippo

It seems to me, therefore, that the sevenfold operation of the Holy Spirit, of which Isaiah speaks, coincides with these stages and maxims. However, the order is different. In Isaiah, the enumeration begins from the higher, while here it begins from the lower; in the former, it starts from wisdom and ends at the fear of God. But "the fear of the Lord is the beginning of wisdom." Therefore, if we ascend step by step, as it were, while we enumerate, the first grade is the love of God; the second is piety; the third is knowledge; the fourth is fortitude; the fifth is counsel; the sixth is understanding; the seventh is wisdom. The fear of God coincides with the humble, of whom it is here said, "Blessed are the poor in spirit."
