It all depends on what your goals are as a counselor. A Christian counselor may be more rewarding for you personally but religious organizations, as rule, doesn't pay much. I'm not sure about job security. That would be based on where you live and the opportunities available in that area. You would need to go to a religiously affiliated school to get a degree in Christian counseling, and private schools tend to be more expensive than state secular colleges and universities. There seem to be many colleges online that offer advance degrees in Christian couneling but I would advise you to check on how legitimate they are and whether their degrees have any value. But I would encourage you to speak to your pastor or priest about Christian counseling and get that person's perspective. It's possible that your church would be able to sponsor you and help with your education if you are serious and indicate that you may be willing to work with the parishoners there. If there are volunteer opportunities in your church you should to try some of those. Finally, this again has to do with what your goals are. As a secular counselor you would have a broader base of possible clients and patients, people from different religious and theological backgrounds and some who are not believers. So you would have to be prepared to deal with all sorts of issues, some of which you might find personally distasteful or unsettling.
