1 Samuel 14:33

They reported to Saul, saying that the people had sinned against the Lord, etc. The diligent leaders, knowing the negligence of idle teachers, wherein the people sin against the Lord, baptizing those who have not yet been purified from carnality nor fully instructed in faith, immediately rebuke such transgressors and command that the rule of heavenly life be openly proposed with Catholic authority; and they order the idle teachers, who had so far been vexed by common ignorance, to lead all those they have undertaken to instruct up to the model of life which they themselves had learned from their forefathers, and by catechizing them according to the most robust example of Catholic perfection, bring to an end their former way of life inherited from their fathers, and by baptizing, incorporate them into the members of the Church. Thus, they would no longer sin against the Lord, binding those who are ignorant of faith and heavenly life to the unity of His body, that is, the Church of Christ. Understand that the ox and the ram delivered from the Philistines, slaughtered and eaten by the people of God upon the intellectual rock, symbolize any foolish and arrogant person, renewed from deadly custom into spiritual life; as also mentioned above, sheep and calves together with the oxen taken from them signify movements of soul or flesh devoted to irrationality and lust, but saved through the Lord.

It is proper to the preachers of the holy Church both to rebuke committed faults and to show how those rebuked faults ought to be avoided. Once rebuked, they become known, but if people do not know how to avoid them, once exposed they are repeated. What is shown in this eating of blood, if not the hidden poison of pride? But hidden vices are not cured unless they are exposed. Therefore, to suggest the manner of preachers, Saul first declares that the people have transgressed, then commands that the animals they are to eat be slain upon a stone. But we know who the rock or stone is, because Paul showed this, saying: "And the Rock was Christ" (1 Cor. 10:4). The stone is rolled before the preacher when the examples of the Redeemer are recalled in his presence. It is also said to be rolled over, so that it may be seen from every side. It is called great because through Daniel it is reported to grow and fill the whole face of the earth (Dan. 2). Therefore it is not viewed carelessly, but turned from both sides, so that God may be beheld by the arrogant, and their arrogance may be crushed. Let the arrogant one see, then, how powerful in might, how sublime in majesty, how humble in power our Redeemer appeared. For while giving sight to the blind and healing the sick (Matt. 9), he commanded that what he had done powerfully should be told to no one. On the mountain he shone in splendor, the Father brought forth testimony of his divinity, and yet he said to his disciples: "Tell no one of this vision, until the Son of Man has risen from the dead" (Matt. 17:9). And perhaps for this reason, when the Lord was now rising, an angel appeared at the tomb who rolled the stone away from its entrance. For then the stone had to be rolled away, because Christ, true man and mighty God, was to be recognized after the glory of the resurrection. If therefore the proud man has looked at one side of the stone, let him roll the stone and see the other side. Let him not view the stone in just any way, for Christ is not dead, but let him see it rolled away by an angel, because he rose from the dead. Let him behold from one side the eloquence of preaching, and turn it, and marvel from the other side at the splendor of humility. Let him see from this side the power of signs, and from that side let him see that he who shone with the power of might concealed that same might by a command of…
