Psalms 42:4

“Then will I go in unto the Altar of God” ( ver. 4 ). For there is a certain invisible Altar on high, which the unrighteous man approaches not. To that Altar he alone draws nigh, who draws nigh to this one without cause to fear. There he shall find his Life, who in this one “separates his cause.” “And I will go in unto the Altar of God.” From His holy Hill, and from His Tabernacle, from His Holy Church, I will go in unto the Altar of God on High. What manner of Sacrifice is there? He himself who goeth in is taken for a burnt-offering. “I will go in unto the Altar of God.” What is the meaning of what he says, “The Altar of my God”?

[2.] “Unto my God.” Out of great affection he seizes on that which is common, and makes it his own; as the prophets also from time to time use to say, ( Ps. xliii. 4; lxii. 1 .) “O God, my God;” and by way of encouragement he incites them to use the same language also themselves. For such expressions belong to one who is retiring from all secular things, and moving towards Him whom he calls on with so much earnestness: since he alone can truly say this, who from things of this life is ever mounting upwards unto God, and always preferring Him to all, and giving thanks continually, not [only] for the grace already given, but whatever blessing hath been since at any time bestowed, for this also he offereth unto Him the same praise. …

4. But God, who is good, multiplied His loving-kindness towards us, not only when He granted the common salvation of us all through His Word, but now also, when enemies have persecuted us, and have sought to seize upon us. As the blessed Paul saith in a certain place, when describing the incomprehensible riches of Christ: ‘But God, being rich in mercy, for the great love wherewith He loved us, even when we were dead in follies and sins, quickened us with Christ.’ For the might of man and of all creatures, is weak and poor; but the Might which is above man, and uncreated, is rich and incomprehensible, and has no beginning, but is eternal. …

43. The cleansed people, rich with these adornments, hastens to the altar of Christ, saying: “I will go to the altar of God, to God Who maketh glad my youth;” for having laid aside the slough of ancient error, renewed with an eagle’s youth, it hastens to approach that heavenly feast. It comes, and seeing the holy altar arranged, cries out: “Thou hast prepared a table in my sight.” David introduces the people as speaking, where he says: “The Lord feedeth me, and nothing shall be wanting to me, in a place of good pasture hath He placed me. He hath led me forth by the water of refreshment.” And later: “For though I walk in the midst of the shadow of death, I will fear no evils, for Thou art with me. Thy rod and Thy staff have comforted me. Thou hast prepared in my sight a table against them that trouble me. Thou hast anointed my head with oil, and Thy inebriating cup, how excellent it is!”

17. What a procession shall that be, what joy of applauding angels when she is found worthy of dwelling in heaven who lived on earth a heavenly life! Then too Mary, taking her timbrel, shall stir up the choirs of virgins, singing to the Lord because they have passed through the sea of this world without suffering from the waves of this world. Then each shall rejoice, saying: “I will go to the altar of God; to God Who maketh my youth glad;” and, “I will offer unto God thanksgiving, and pay my vows unto the Most High.”

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 …
