In this text, St. Paul is warning the Corinthians about it. He says, ‘You may be Christian men; you may have the means of grace; you may come to the Communion and use the means of grace; and yet you may become castaways.’ St. Paul himself says, in the very verse before, ‘I keep under my body, and bring it into subjection: lest . . . . I myself should be a castaway.’ Look, he says then, ‘at the old Jews in the wilderness. They all partook of God’s grace: but they were not all saved. They were all baptized to Moses in the cloud and in the sea. They all ate the same spiritual meat, the manna from heaven. They all drank the same spiritual drink, the water out of the rock in Horeb. And yet with many of them God was not well pleased;’ for they were overthrown—their corpses were scattered far and wide—in the wilderness. The spiritual meat and the spiritual drink could not keep them alive, if they sinned, and deserved death. ‘So,’ says St. Paul, ‘with you. You are members of Christ’s body. The cup of blessing which we bless, is the communion of the blood of Christ; the bread which we break, is the communion of the body of Christ:’ but beware, they will not save you, if you sin. Nothing will save you, if you sin. If you lust after evil things, as those old Jews did; if you are idolaters, as they were; if you are profligates, as they were; if you tempt Christ, as they did; if you murmur against God, as they murmured, you will be destroyed like them.
Note here two things. First, that St. Paul says that we really receive Christ in the Holy Communion. He does not say, as some do, that the Communion is merely a remembrance of Christ’s death. He says that the faithful verily and indeed receive Christ’s body and blood in the Sacrament. He says so, distinctly, plainly, literally; and if that be not true, his whole argument goes for nothing, and will not stand. The Jews, he says, drank of the spiritual Rock which followed them, and that Rock was Christ; and so he says to you. But that did not save them from the punishment of their sins, when they went and sinned afresh: neither will it save you.
But now—What are these strange words which St. Paul uses? These old Jews drank of the spiritual Rock which followed them, and that Rock was Christ? Where in the Old Testament do we read of the Rock following them? We read of Moses striking the rock in Horeb, at the beginning of their wanderings in the wilderness; but not of its following them afterwards.
St. Paul is here using a beautiful old tradition of the Rabbis, that the rock which Moses struck in Horeb followed the Jews through all their forty years’ wanderings, and that on every Sabbath day when they stopped, it stopped also, and the elders called to it, ‘Flow out, O fountain,’ and the water flowed. A beautiful old story, which St. Paul turns into an allegory, to teach, as by a picture, the deepest and the highest truth. Whether that rock followed them or not, he says, there was One who did follow them, from whom flowed living water; and that Rock is Christ. Christ followed them. Christ the creator, the preserver, the inspirer, the light, the life, the guide of men, and of all the universe. It was to Christ they owed their deliverance from Egypt; to Christ they owed their knowledge of God, and of the law of God, to Christ they owed whatever reason, justice, righteousness, good government, there was among them. And to Christ we owe the same.
The rock was a type of him from whom flows living water. As he himself said on earth, ‘Whosoever drinketh of the water which I shall give him, shall never thirst; but the water which I shall give him shall be in him a well of water, springing up to everlasting life.’ Just as the manna also was a type of him, as he himself declared, when the Jews talked to him of the manna; ‘Our fathers did eat manna in the desert, as it is written, He gave them bread from heaven to eat.’ Then Jesus said to them, ‘Verily, verily, I say unto you, Moses gave you not that bread from heaven.’ No: but only a type and picture of it. ‘My Father giveth you the true bread from heaven. For the bread of God is he which cometh down from heaven, and giveth life unto the world. . . . I am that bread of life.’
My friends, herein is a great mystery. Something of what it means, however, we may learn from that wise and good Jew, Philo, who was St. Paul’s teacher according to the flesh, before he became a Christian; and who himself was so near to the kingdom of God, that St. Paul often in his epistles uses Philo’s very words, putting into them a Christian meaning. And what says he concerning the Rock of living waters?
The soul, he says, falls in with a scorpion in the wilderness; and then thirst, which is the thirst of the passions—of the lusts which war in our members—seizes on it; till God sends forth on it the stream of his own perfect wisdom, and causes the changed soul to drink of unchangeable health. For the steep rock is the wisdom of God (by whom he means the Word of God, whom Philo knew not in the flesh, but whom we know, as the Lord Jesus Christ), which, being both sublime and the first of all things; he quarried out of his own powers; and of it he gives drink to the souls which love God; and they, when they have drunk, are filled with the most universal manna.
So says Philo, the good Jew, who knew not Christ; and therefore he says only a part of the truth. If you wish to learn the whole truth, you must read St. John’s Gospel, and St. Paul’s Epistles, especially this very text; and again, the opening of the Epistle to the Ephesians; and again, that most royal passage in the opening of the Colossians, where he speaks of the Everlasting Being of Christ, who is before all things, and by whom all things consist—in whom dwells all the fulness of the Godhead bodily, and in whom are hid all the treasures of wisdom and knowledge.
Therefore he is rightly called the Rock, the Rock of Ages, the Eternal Rock; because on him all things rest, and have rested since the foundation of the world, being made, and kept together, and ruled, and inspired by him alone. Therefore he is rightly called the Rock of living waters; for in him are hid all the treasures of wisdom and knowledge, and from him they flow forth freely to all who cry to him in their thirst after truth and holiness. Yes, my friends, by Christ all things live; and therefore, most of all, by Christ our souls live. To be parted from Christ is death. To be joined to Christ and the body of Christ is life.
But what life? The life of the soul. And what is the life of the soul? Holiness, righteousness, sanctification, virtue,—call it what pleases you best. I shall call it goodness. That is the only life of the soul. And why? Because it is the life of Christ. That is the only wisdom of the soul. And why? Because it is the mind of Christ. That is the living water. And why? Because it flows eternally from Christ.
