Depending on the specific college, some or all religious activities may be required. Many Faith-based colleges are still focused on promoting faith and spiritual growth for their students, even if they are not necessarily as forward about it as many Christian colleges. They may still offer chapels, devotions, Bible studies, and Campus ministries events.
In some cases, they may even require students to attend chapels or take a certain number of Bible-related courses. Though this is not as common in Faith-based colleges as it is in Christian colleges, it isn't unheard of. In these cases, whether students consider themselves Christian or not, they would still be required to attend chapels or take the assigned classes, as per the university's rules and requirements.
Of course, not every Faith-based college requires chapel attendance, participation in religious activities, or even Bible classes. Just because they don't require these things doesn't mean that they won't offer or encourage them. To find out what sort of religious requirements or offers a Faith-based university has, check their website or contact their admissions department.
