Rev 6:6

“"Hurt not the wine and the oil." That is, strike not the spiritual man with thy inflictions. This is the black horse.”

“He is speaking of the church in the figures of the wheat and barley. He speaks either of those who are great and who are least in the church or of those who are leaders and the people. However, one two-pound weight is no less than three two-pound weights, for the same perfection subsists both in the unity and in the trinity. Thus, the Lord said that the leaven was hidden in the three measures of meal, showing the teaching of wisdom that from something small the whole people are consecrated by the mystical number of the undivided Trinity. But this teaches also that there is one price for both the wheat and the barley, that is, that although one person may exceed another in merit, both have nevertheless been redeemed by one price.”

“The wine is to be interpreted as the blood of Christ, and the oil as the unction of chrismation.”

“I think that the different numbers of one and three are mentioned on account of the diversity of personal habitations. In the one denarius is indicated eternal life that is common to all even though [they live] among many mansions. And if one is there regarded as more sublime than another according to merits or is given a greater reward, yet no one is thought to be preeminent in comparison with another. For where there is a single immortality to each, there a common eternity exists for all. So also in the wine and oil he prohibits the dishonoring of the power of the sacraments, since that is the chrismation and the precious blood. Therefore we read, "What does he have which is good and beautiful, unless it be the fruit of the elect and producing virgins as wine." And in the psalm: "Wine gladdens the heart of man, and his face is made cheerful in oil."”

“The phrase "a quart of wheat for a denarius" figuratively indicates those who have struggled lawfully and have carefully preserved the divine image given to them. The phrase "three quarts of barley for a denarius" speaks of those who like cattle have through cowardice bowed the neck to persecutors but have later repented and have washed their defiled image with tears. The command "do not harm wine and oil" indicates that the healing of Christ through repentance, which healed him who fell among the thieves, ought not be rejected, nor that those be allowed to be seized prematurely by death who through patience would be retrieved from defeat. Therefore, that we also might possess God as our beneficent physician for the suffering of our souls, let us be zealous to be such to our brothers who have fallen, bringing to them the wine of consolation mixed with the oil of compassion, "so that what is lame may not be put out of joint but rather be healed," as the apostle says. And so becoming fellow workers with God, we may eternally enjoy his blessings by the grace and good will of our Lord, Jesus Christ.”

“A measure of wheat for a denarius, etc. He says, Beware lest you scandalize your brother by a very bad example, for whom Christ died and who bears the marks of the sacred blood and chrism. For whether by the merits of the perfect, or even of the least, anyone in the Church imbued with faith in the Holy Trinity is redeemed at the same perfect price of the Lord's blood. And not without reason is the perfection of faith or work expressed by a double measure and not a single one, which both consist in the root of twin charity.”

“And I heard as it were a voice in the midst of the four living creatures, saying: Two pounds of wheat for a penny, and thrice two pounds of barley for a penny, and see thou hurt not the wine and the oil. This voice sounded in the midst of the four living creatures, that is in the midst of the Church, when, after the nations had been united in faith, the divine power restrained the Devil from hurting the elect; as if he were told by mockery, "The rider of the white horse has chosen and purchased the wheat, barley, wine, and oil for one penny; and he has left for you the chaff, husks, and oil dregs." So one two-pound measure, which is made up of two sextarii, is the Church based on love of God and neighbor from the two Testaments. However we should understand here one Church consisting of the holy preachers or men of great merit, not of everyone in general. Indeed it is not without reason that barley is here mentioned after the wheat. Therefore let us take the two pounds of wheat as representing the new preachers of the Church, coming from two peoples, and men more outstanding in virtues, who, after being shattered by the mill of tribulations and cooked by the fire of persecutions, have deserved to become a beautiful white bread for Christ. Let us take thrice two pounds of barley as representing the lives of the inferiors and weak from both peoples. Note also that the price of the wheat and of the barley is the same, because even though the work of the saints is unequal, they were nonetheless bought for the same price, and they will receive the same penny after their work. [Ref. Matt. 20:1-16] Furthermore, it should be noted that the same idea is repeated when it is said afterwards See thou hurt not the wine and the oil. How indeed could the Church not be wine and oil when it is trodden like a grape in the wine press of oppressions and dissolved as a crushed olive in the oil press of straits?”

“QUESTION: What is meant by Two pounds of wheat for a penny, and thrice two pounds of barley for a penny, and see thou hurt not the wine and the oil? ANSWER: He is saying: Be careful not to entice your brother into sin through bad example, your brother for whom Christ died, and who wears the signs of the sacred blood and unction; because Church members, from those who are perfect in merits to those who are the least ones in the Church but are nonetheless imbued with faith in the holy Trinity, have all been redeemed for the perfect price of the Lord's blood. It is also not without reason that perfection in faith or work is represented by two pounds rather than a single one, because both are based on the root of the double love.”
