Is it safe for the children of believers to enroll in universities founded by Seventh-day Adventists, Roman Catholics, or non-Christian educational institutions?

First and foremost, we must acknowledge that these schools are religious institutions. And part of their mission is to convert as many students to their faith as possible by exposing them to their doctrines, whether acknowledged or not. It is possible to say the same thing about the schools that are owned and run by a large number of evangelical Christians. Even government universities that claim to be non-religious but do not include any religious practice or subject strive to remove God from their system, so indirectly encouraging atheism. If a parent believes that the school or university in question is the best institution in their area for primary education and college degrees, they must ensure that their children have a thorough understanding of the Christian faith. This will keep their children from becoming doctrinally confused or converted by non-Christian educational establishments. Christian parents can also teach their children how to engage and evangelize their classmates and friends in a friendly way. If parents are not mindful of their Christian faith, there is a high probability that their children will be convinced by the teachings of these religious educational institutions. “Train up a child in the way he should go; even when he is old he will not depart from it.” Proverbs 22:6
