The elements are worshipped,--the air by Diogenes, the water by Thales, the fire by Hippasus; and by those who suppose atoms to be the first principles of things, arrogating the name of philosophers, being wretched creatures devoted to pleasure. “Wherefore I pray,” says the apostle, “that your love may abound yet more and more, in knowledge and in all judgment, that ye may approve things that are excellent.”[907] “Since, when we were children,” says the same apostle, “we were kept in bondage under the rudiments of the world. And the child, though heir, differeth nothing from a servant, till the time appointed of the father.”[908] Philosophers, then, are children, unless they have been made men by Christ. “For if the son of the bond woman shall not be heir with the son of the free,”[909] at least he is the seed of Abraham, though not of promise, receiving what belongs to him by free gift. “But strong meat belongeth to those that are of full age, even those who by reason of use have their senses exercised to discern both good and evil.”[910] “For every one that useth milk is unskilful in the word of righteousness; for he is a babe,”[911] and not yet acquainted with the word, according to which he has believed and works, and not able to give a reason in himself. “Prove all things,” the apostle says, “and hold fast that which is good,”[912] speaking to spiritual men, who judge what is said according to truth, whether it seems or truly holds by the truth. “He who is not corrected by discipline errs, and stripes and reproofs give the discipline of wisdom,” the reproofs manifestly that are with love. “For the right heart seeketh knowledge.”[913] “For he that seeketh the Lord shall find knowledge with righteousness; and they who have sought it rightly have found peace.”[914] “And I will know,” it is said, “not the speech of those which are puffed up, but the power.” In rebuke of those who are wise in appearance, and think themselves wise, but are not in reality wise, he writes: “For the kingdom of God is met in word.”[915] It is not in that which is not true, but which is only probable according to opinion; but he said “in power,” for the truth alone is powerful. And again: “If any man thinketh that he knoweth anything, he knoweth nothing yet as he ought to know.” For truth is never mere opinion. But the “supposition of knowledge inflates,” and fills with pride; “but charity edifieth,” which deals not in supposition, but in truth. Whence it is said, “If any man loves, he is known.”[916] CHAPTER XII. THE MYSTERIES OF THE FAITH NOT TO BE DIVULGED TO ALL.
