I think I've posted this a couple times already, but I'll post it again with careful emphasis...
-- 1 Corinthians 5:9-11
To get their "daughter" into that school, they proclaimed themselves adherent to that Christian school's Article of Faith. In the process, they lied to accomplish this. In addition, they proudly persist in their sin while their "daughter" takes their part over God's.
Do you see why the school has no choice but to dissolve their association with this family?
I do. I also see a child being sacrificed on the profane altar of 'Gay Rights' by two scheming homosexuals, which is the worst part of it all.
