Psalms 42:3

4. But in order that she may do this, hear what she says, what she supplicates, what she prays for. Pray thou for what thou hearest; pray for it when thou hearest it; let these words be the voice of us all: “O send out Thy Light and Thy Truth. They have led me, and brought me on unto Thy holy hill, and into Thy Tabernacles” ( ver. 3 ). For that very “Light” and “Truth” are indeed two in name; the reality expressed is but One. For what else is the “Light” of God, except the “Truth” of God? Or what else is the “Truth” of God, except the “Light” of God? And the one Person of Christ is both of these. …

6. Such then, as we have above described, is the madness and daring of those men. But our faith is right, and starts from the teaching of the Apostles and tradition of the fathers, being confirmed both by the New Testament and the Old. For the Prophets say: ‘Send out Thy Word and Thy Truth,’ and ‘Behold the Virgin shall conceive and bear a son, and they shall call His name Emmanuel, which is being interpreted God with us.’ But what does that mean, if not that God has come in the Flesh? While the Apostolic tradition teaches in the words of blessed Peter, ‘Forasmuch then as Christ suffered for us in the Flesh;’ and in what Paul writes, ‘Looking for the blessed hope and appearing of our great God and Saviour Jesus Christ, Who gave Himself for us that He might redeem us from all iniquity, and purify unto Himself a people for His own possession, and zealous of good works.’ How then has He giv …

XXXVI. I will remind you again about Illuminations, and that often, and will reckon them up from Holy Scripture. For I myself shall be happier for remembering them (for what is sweeter than light to those who have tasted light?) and I will dazzle you with my words. There is sprung up a light for the righteous, and its partner joyful gladness. And, The light of the righteous is everlasting; and Thou art shining wondrously from the everlasting mountains, is said to God, I think of the Angelic powers which aid our efforts after good. And you have heard David’s words; The Lord is my Light and my Salvation, whom then shall I fear? And now he asks that the Light and the Truth may be sent forth for him, now giving thanks that he has a share in it, in that the Light of God is marked upon him; that is, that the signs of the illumination given are impressed upon him and recognized. …

147. God has as an attribute that He is true for it is written: “Let God be true and every man a liar.” Does the Spirit lie Who is the Spirit of Truth? and Whom we have shown to be called the Truth, since John called Him too the Truth, as also the Son? And David says in the psalm: “Send out Thy light and Thy truth, they have led me and brought me to Thy holy hill and to Thy tabernacles.” If you consider that in this passage the Son is the light, then the Spirit is the Truth, or if you consider the Son to be the Truth, then the Spirit is the light.

Isaac : Not every kind of shedding of tears is produced by one feeling or one virtue. For in one way does that weeping originate which is caused by the pricks of our sins smiting our heart, of which we read: “I have laboured in my groanings, every night I will wash my bed; I will water my couch with my tears.” And again: “Let tears run down like a torrent day and night: give thyself no rest, and let not the apple of thine eye cease.” In another, that which arises from the contemplation of eternal good things and the desire of that future glory, owing to which even richer well-springs of tears burst forth from uncontrollable delights and boundless exultation, while our soul is athirst for the mighty Living God, saying, “When shall I come and appear before the presence of God? My tears have been my meat day and night,” declaring with daily crying and lamentation: “Woe is me that my sojourn …
