Devote ourselves to prayer…

But we must above all devote ourselves to prayer; for prayer is like a choir-leader in the choir of virtues, by means of which we ask God for the virtues we still lack. Devotion to prayer unites the Christian to God in the communion of a mystic sanctity, in a spiritual possession and a disposition of the soul that no words can describe. With the Spirit then to guide and help him, his love for the Lord like a bright flame, he prays unceasingly in ardent desire, always burning with love for the divine good and refreshing his soul with renewed zeal.
–Saint Gregory of Nyssa (c. 335 – c. 395)

For the quality of holiness is shown…

When we consider that Christ is the true light, we learn that our own life also must shine with the rays of that true light. Now these rays of the Sun of Justice are the virtues which pour out to enlighten us. If we truly think of Christ as our source of holiness, we shall refrain from anything wicked or impure in thought or act and thus show ourselves to be worthy bearers of his name. For the quality of holiness is shown not by what we say but by what we do in life.
— Saint Gregory of Nyssa (c. 335 – c. 395)

On human nature….

Sick, our nature demanded to be healed; fallen, to be raised up; dead, to rise again. We had lost the possession of the good; it was necessary for it to be given back to us. Closed in the darkness, it was necessary to bring us the light; captives, we awaited a Savior; prisoners, help; slaves, a liberator. Are these things minor or insignificant? Did they not move God to descend to human nature and visit it, since humanity was in so miserable and unhappy a state?
— Saint Gregory of Nyssa (c. 335 – c. 395)

When the mystery sanctifies…

The bread again is at first common bread; but when the mystery sanctifies it, it is called and actually becomes the Body of Christ. So too the mystical oil, so too the wine; if they are things of little worth before the blessing, after their sanctification by the Spirit each of them has its own superior operation. The same power of the word also makes the priest venerable and honorable, separated from the generality of men by the blessing bestowed upon him. Yesterday he was but one of the multitude, one of the people; suddenly he is made a guide, a president, a teacher of piety, an instructor in hidden mysteries.
–Saint Gregory of Nyssa (c. 335 – c. 395)

Life has begun…

The reign of life has begun, the tyranny of death is ended. A new birth has taken place, a new life has come, a new order of existence has appeared, our very nature has been transformed! This birth is not brought about by human generation, by the will of man, or by the desire of the flesh, but by God. If you wonder how, I will explain in clear language. Faith is the womb that conceives this new life, baptism the rebirth by which it is brought forth into the light of day. The Church is its nurse; her teachings are its milk, the bread from heaven is its food. It is brought to maturity by the practice of virtue; it is wedded to wisdom; it gives birth to hope. Its home is the kingdom; its rich inheritance the joys of paradise; its end, not death, but the blessed and everlasting life prepared for those who are worthy.
— Saint Gregory of Nyssa (c. 335 – c. 395)
