From a Christian point of view, the new "Relationships and Sex Education (RSE)" regulations amount to compulsory, immoral grooming of an entire nation's children. Children will be indoctrinated in the teachings of the sexual revolution, encouraged to experiment, taught about sexuality in an amoral context, and in some items taught definite immorality and that it is wrong not to be open to all kinds of harmful, damaging at extreme ideas (the ideas themselves, not just kind to the people misled by them). And, for some of this (and all of it for some), opting out will be forbidden. And this teaching will go on at their most vulnerable ages, throughout the whole process of turning from an infant into an adult: drip-feed indoctrination from infancy, offering of perversion and confusion as live options as they go through adolescence, puberty and sexual awakening, etcetera.
Again I ask, what are Christians planning to do about this? The crunch comes. Are we going to voluntarily send along our children to be groomed week by week? Do we intend just to turn a blind eye, or trust in a cunning plan to undo this out of hours? We're going to immerse vulnerable young minds throughout the day, throughout the working week, in a context in which they're continually bombarded with messages (carefully crafted, with large amounts of funding behind them) that we're wrong, that and then tell them it's wrong, and hope for the best? Is that our idea of what it means to "bring them up in the discipline and instruction of the Lord" (Ephesians 6:4), and to surround them with discussion and encouragement in the good law of God throughout their childhood (Deuteronomy 6:4-9)?
The hour is late. But it's never too late to do the right thing, and entrust ourselves to God. For churches and church leaderships, that means coming together to make sure that there is full support available - including, if there are none available, Christian schools - for the Christian education of our children. Their raising in the nurture and admonition of the Lord, rather than grooming in the doctrines of depravity. (Those two things really are different, and the difference matters). For parents, that means not sending your children along to compulsory grooming. If not sending them is against the rules, then break the rules. We must obey God rather than men. You'll get invited to speak to the headmaster, you'll get fined for truancy: pay the fines, or don't pay them,
but don't send your children for compulsory grooming. If they escalate it, withdraw your children (or withdraw them first before giving them an (unfair) stick to beat you with). Educate them in a school, a co-op, or a home (or a combination of all three) where there's no compulsory grooming, and where there is godly teaching.
Will you have to pay a cost? Of course you will, you will have to take up your cross daily, and follow Christ. Are you signed up for that, or not?
