Liberty U is a school that people feel very strongly about - either positively or negatively. The school has firm positions and they live them out. If you are applying for a job with someone who feels similarly, that will be a plus. However there are significant numbers of people who disagree with much of what Liberty espouses, so the degree would be a negative to them.
If your beliefs align with Liberty, then it may be the best choice for you. If not, I would look for somewhere less polarizing to do your advanced religious studies.
