1. Absurdity.—It maketh void all those scriptures that do affirm the doctrine; some of which you have before.
2. Absurdity.—If in the Godhead there be but one, not three, then the Father, Son, or the Spirit, must needs be that one, if any one only: so then the other two are nothing. Again, If the reality of a being be neither in the Father, Son, nor Spirit, as such, but in the eternal deity, without consideration of Father, Son, and Spirit as three; then neither of the three are anything but notions in us, or manifestations of the Godhead; or nominal distinctions; so related by the word; but if so, then when the Father sent the Son, and the Father and Son the Spirit, one notion sent another, one manifestation sent another. This being granted, this unavoidably follows, there was no Father to beget a Son, no Son to be sent to save us, no Holy Ghost to be sent to comfort us, and to guide us into all the truth of the Father and Son, &c. The most amounts but to this, a notion sent a notion, a distinction sent a distinction, or one manifestation sent another. Of this error these are the consequences, we are only to believe in notions and distinctions, when we believe in the Father and the Son; and so shall have no other heaven and glory, than notions and nominal distinctions can furnish us withal.
3. Absurdity.—If Father and Son, &c., be no otherwise three, than as notions, names, or nominal distinctions; then to worship these distinctly, or together, as such, is to commit most gross and horrible idolatry: For albeit we are commanded to fear that great and dreadful name, The Lord our God; yet to worship a Father, a Son, and Holy Spirit in the Godhead, as three, as really three as one, is by this doctrine to imagine falsely of God, and so to break the second commandment: but to worship God under the consideration of Father, and Son, and Holy Ghost, and to believe them as really three as one when I worship, being the sum and substance of the doctrine of the scriptures of God, there is really substantially three in the eternal Godhead.
But to help thee a little in thy study on this deep.
1. Thou must take heed when thou readest, there is in the Godhead, Father, and Son, &c., that thou do not imagine about them according to thine own carnal and foolish fancy; for no man can apprehend this doctrine but in the light of the word and Spirit of God. "No man knoweth the Son, but the Father; neither knoweth any man the Father, save the Son; and he to whom the Son will reveal him" (Matt 11:27). If therefore thou be destitute of the Spirit of God, thou canst not apprehend the truth of this mystery as it is in itself, but will either by thy darkness be driven to a denial thereof; or if thou own it, thou wilt (that thy acknowledgment notwithstanding) falsely imagine about it.
2. If thou feel thy thoughts begin to wrestle about this truth, and to struggle concerning this one against another; take heed of admitting of such a question, How can this thing be? For here is no room for reason to make it out, here is only room to believe it is a truth. You find not one of the prophets propounding an argument to prove it; but asserting it, they let it lie, for faith to take it up and embrace it.
"The grace of the Lord Jesus Christ, and the love of God, and the communion of the Holy Ghost, be with you all. Amen" (2 Cor 13:14).
III. Of the Creation of the World (Gen 1).
The Apostle saith, That "to us there is but one God, the Father, of whom are all things, and we in him, and one Lord Jesus Christ, by whom are all things, and we by him" (1 Cor 8:6). "God that made the world" (Acts 17:24). "All things were made by him; and without him was not any thing made that was made" (John 1:3). This world therefore had a beginning, and was created by the God of heaven. Which work, because it is wonderful, and discovereth much of the greatness, of the wisdom and power of the eternal Godhead, it behoveth such poor mortals as we to behold these works of the mighty God, that thereby we may see how great he is, and be made to cry out, What is man! [2] (Psa 8:3,4)
Now in the creation of the world we may consider several things; as, What was the order of God in this work? And, whether there was a secret or mystery in this work containing the truth of some higher thing? For the first of these:
