Hosea 4:6 says that the "people are destroyed for lack of knowledge." Children today are bibically illiterate. The Christian preacher/pastor is called to contend earnestly for the Faith - not the faiths. Paul tells Timothy to preach the faith, in-season and out of season...again, not the "faiths."
This is a really a sad story, not an encouraging one.
Rom 9:33 As it is written, Behold, I lay in Sion a stumblingstone and rock of offence: and whosoever believeth on him shall not be ashamed.
This chaplain is attempting to not bring offense. But we are told that Jesus is a stumbling block and an offense to those who refuse the gospel.
This is just another sad incidence of Christians desiring to please man, rather than God.
Better would be the approach of one Christian school which was upfront with parents and stated in their enrollment interview that they could expect that their child would be taught what it meant to come to a saving knowledge of Christ. Or the experience of the local Catholic school which had enrolled Muslim children whose parents then objected to the Christain teachings: "take your child elsewhere then; we will not cease being Catholic to accommodate your child."
