“so-called Christian teachers “
I suggest you find a strong Christian and discuss this phrase and the danger of persecuting Christians who are fulfilling their calling by teaching in public schools.
I strong suggest that Christian teachers re-evalute their "calling". When God and His Son Jesus are scrubbed from the the curriculum and textbooks then this is not religiously neutral. Education is one or the other. It on side of the fence with Jesus, or it is on the side against Jesus. It is also not what the Christian teacher KNOWS to be the complete truth.
What are Christian teachers doing every day?
Are they praying to God and asking Him to help them teach half the truth?
Are they praying for help in promoting the anti-god religious philosophy of the government school?
Are they asking for extra grace to help them be sneaky and sly so they squeeze a grain of Christianity into the lesson plan.
Or...Are they asking God to help them be lukewarm in proclaiming the gospel so they can prostitute themselves for their paycheck?
Personally, I think these teachers are making it harder for real missionaries that their students may meet later in their adult lives. What former government school students will have learned from their Christian teachers is that Christians are sly, sneaky, lukewarm, weak, wimpy, and will sell their souls and an anti-god worldview for a paycheck.
I never had a moment of silence mandated for anything when I was in public schools. It never stopped me, my friends, or my “so called Christian” teachers from praying. Never.
The readers on this board know that free speech of all kinds ( especially religious speech), free press, ( especially about religion), free expression of religion, and free association, are all tightly controlled in the government schools.
If a parent can not afford to ransom their child by paying private or home school expenses, then that parent must make "Sophie's Choice": government indoctrination camp ( mis-named "school") or prison. If he is sufficiently resistant armed police will kill him. Just ask John Singer.
