See the unity wherein Father and Son are plainly revealed. “In these words attention is called to the Unity of Nature (or Substance) in distinct Persons, for in the very act of speaking and teaching, the Son shows that He is a Person, but He Who speaks not of Himself, but as the Father hath taught Him, shows that He is distinct from the Father, and yet He has, with the Father, one and the same doctrine, and therefore one and the same nature; for, in God, being and knowing are one and the same.”—Hurter. He who speaks cannot but be; yet that which He speaks cannot be solely from Him, for in Him all that is, is naturally derived from the Father.
