8. Certainly enough, then, Christ is the man to whom Moses refers as God. Thus the testimony of Moses long before is identical with that of Paul. Though employing different terms, they both confess Christ as the Son of God, born in eternity of the Father, in the same divine essence and yet distinct from him. You may call this difference what you will; we indicate it by the term "person." True, we do not make a wholly clear explanation of the mystery; we but stammer when speaking of a "Trinity." But what are we to do? we cannot better the attempt. So, then, the Father is not the Son, but the Son is born of the Father in eternity; and the Holy Spirit proceeds from God the Father and God the Son. Thus there are three persons, and yet but one God. For what Moses declares concerning God Paul says is spoken of Christ. 9. The same argument substantially Paul employs in Acts 20, 28, when, blessing the Church of Miletus and exhorting the assembled ministers concerning their office, he says: "Take heed unto yourselves, and to all the flock, in which the Holy Spirit hath made you bishops, to feed the church of the Lord which he purchased with his own blood." This, too, is a significant text, proving beyond all controversy that Christ our Lord, who purchased the Church with his blood, is truly God, and to him the Church belongs. For the apostle plainly asserts it was God who bought the Church with his blood and that the Church is his own. Now, in view of the fact already established that the persons are distinct, and of the further statement that God has purchased the Church through his own blood, we inevitably conclude that Christ our Saviour is true God, born of the Father in eternity, and that he also became man and was born of the Virgin Mary in time. 10. If such blood--the material, tangible, crimson blood, shed by a real man--is truly to be called the blood of God, then he who shed it must be actually God, an eternal, almighty person in the one divine essence. In that case we truly can say the blood flowing from the side of the crucified One and spilled upon the ground is not merely the blood of an ordinary man, but God's own. Paul does not indulge in frivolous talk. He speaks of a most momentous matter; and he is in dead earnest when he in his exhortation reminds us that it is an exalted office to rule the Church and to feed it with the Word of God. Lest we toy in the performance of such an office we are reminded that the flock is as dear to him as the blood of his dear Son, so precious that all creatures combined can furnish no equivalent. And if we are indolent or unfaithful, we sin against the blood of God and become guilty of it, inasmuch as through our fault it has been shed in vain for the souls which we should oversee.
