"Do you suppose," says Chrysostom, "that this will be reckoned to you as merit? Elsewhere he says the same: 'Neither if we eat are we the better, nor if we do not eat are we the worse' (cf. 1 Cor 8:8). Here there is no need to prove anything, but only to state it. The meaning of the apostolic words is this: if you eat, will this bring you into the kingdom?"
What, then, brings one into the kingdom? What are its blessings? What serves as a sign that someone belongs to its heirs? "Righteousness and peace and joy in the Holy Spirit." "A virtuous life, peace with one's brother, and joy arising from concord" (Chrysostom). "True righteousness in peace and love, concord and zeal, by which gladness according to God is begotten, acquire the kingdom for us" (Blessed Theodoret).
Righteousness is not only justification and remission of sins. It is inward righteousness, which has cast every unrighteous thing out of the heart and implanted in it right feeling and right thought. From these come right speech and right action. In a word, it is holiness, ready for every good work and strong to accomplish it.
Peace is a peaceful ordering within oneself, in thoughts and feelings, as a result of deliverance from the troubling passions of self-pleasing. It is peace descending from above and overshadowing the soul with the sense of God's good pleasure.
This is guarded by the consciousness that nothing unrighteous has been voluntarily allowed. It gives boldness to look joyfully toward the all-bountiful God. It is also the peace of love with all the brethren, making one soul of all. It enriches each with the sense of the power of such a life, composed of all lives joined in a peaceful union of hearts.
Joy is not something sensory. It is detached from all sensory things and detaches us from them. It does not carry one outside oneself, as usual joy does, but deepens one within oneself. There the heart is given to taste the gladdening blessings "which eye has not seen" (1 Cor 2:9).
From this unceasing tasting joy flows forth, which cannot be purchased by anything else. Joy is inseparable from life, but true joy exists only in spiritual life. Psychic and sensory life have only fleeting joys, always troubled and unpeaceful.
True joy belongs inseparably to spiritual life because this life is established only through union with the all-blessed God by His grace. The all-blessed God pours unceasing joy into the heart that is livingly united with Him by faith, love, and hope.
All this is in the Holy Spirit. Although in the Apostle the phrase "in the Holy Spirit" stands in connection only with joy, in the nature of the matter not joy alone, but also peace with righteousness, is only in the Holy Spirit.
The Holy Spirit gives "all things that pertain to life and piety," and therefore makes a man righteous. The Holy Spirit tears our spirit out of the mouths of psychic and bodily passions. By establishing peace within, He keeps it in peace with God and the brethren.
The Holy Spirit also gives joy. Immediately after turning to God, He gives it only as a foretaste and enticement. After purification from the passions, He gives it as a constant, or more or less constant, tasting.
Then the perceptible action of the grace of the Holy Spirit begins in the heart. Spiritual sweetness is inseparable from it, and joy is inseparable from this sweetness. From this it follows that righteousness, peace, and joy, in their true meaning, exist only in Christians. Among Christians, they exist in those in whom the gift of grace has been kindled.
