Further, many also use the fat of milk, called butter, for the lamp, plainly indicating by this enigma the abundant unction of the Word, since He alone it is who nourishes the infants, makes them grow, and enlightens them. Wherefore also the Scripture says respecting the Lord, “He fed them with the produce of the fields; they sucked honey from the rock, and oil from the solid rock, butter of kine, and milk of sheep, with fat of lambs;”[253] and what follows He gave them. But he that prophesies the birth of the child says: “Butter and honey shall He eat.”[254] And it occurs to me to wonder how some dare call themselves perfect and gnostics, with ideas of themselves above the apostle, inflated and boastful, when Paul even owned respecting himself, “Not that I have already attained, or am already perfect; but I follow after, if that I may apprehend that for which I am apprehended of Christ. Brethren, I count not myself to have apprehended: but this one thing I do, forgetting the things which are behind, and stretching forth to those that are before, I press toward the mark, for the prize of the high calling in Christ Jesus.”[255] And yet he reckons himself perfect, because he has been emancipated from his former life, and strives after the better life, not as perfect in knowledge, but as aspiring after perfection. Wherefore also he adds, “As many of us as are perfect, are thus minded,”[256] manifestly describing perfection as the renunciation of sin, and regeneration into the faith of the only perfect One, and forgetting our former sins. CHAPTER VII. WHO THE INSTRUCTOR IS, AND RESPECTING HIS INSTRUCTION. Since, then, we have shown that all of us are by Scripture called children; and not only so, but that we who have followed Christ are figuratively called babes; and that the Father of all alone is perfect, for the Son is in Him, and the Father is in the Son; it is time for us in due course to say who our Instructor is. He is called Jesus. Sometimes He calls Himself a shepherd, and says, “I am the good Shepherd.”[257] According to a metaphor drawn from shepherds, who lead the sheep, is hereby understood the Instructor, who leads the children--the Shepherd who tends the babes. For the babes are simple, being figuratively described as sheep. “And they shall all,” it is said, “be one flock, and one shepherd.”[258] The Word, then, who leads the children to salvation, is appropriately called _the Instructor_[259] (Pædagogue).
