It is contact, association with evil, that is declared to be corrupting. It is totally irresponsible to send covenant children into a society of evil teachers and evildoers. Spiritual life is quenched in the atmosphere of carnal society, and a sort of intoxication quickly comes over him who frequents it. A covenant child in a public school is assaulted from every side by demonic doctrine, profane disputations, coarse jesting, Satanic music, an exaltation of fornication and rebellion, a hatred of lawful authority, and all sorts of deadly temptations. A fifth reason why a covenant child should not attend public school is that a Christian child's education must always be accompanied by Biblical discipline.
Biblical education is never purely an intellectual affair.
It is always to be accompanied with verbal reproof, correction and admonition, and physical chastisement or spanking when necessary. It also presupposes that the goal of such admonition or correction is an acknowledgment of wrongdoing and a change of behavior in a right direction. That is, there is to be repentance leading to a personality and behavioral change. This point raises a few questions regarding public schools. It is common knowledge that discipline in public schools is very lax, if not virtually non-existent.
