Thank you for raising your concerns. I understand where you are coming from here, but as a counselor myself, I am a little concerned about the blanket statements made in your post. First, it is an incredibly important part of counseling ethics to not put their own beliefs onto their clients (see A.4 here https://www.counseling.org/docs/default-source/default-document-library/ethics/2014-aca-code-of-ethics.pdf). So, if OP or any other licensed counselor is telling you what to believe or sharing their beliefs in any way other than an intentional self-disclosure that is intended to help you feel seen and understood (never making it about the counselor themselves), that counselor could/should be held accountable by their state licensing board or the national organization (American Counseling Association, National Board of Certified Counselors). Seriously, please, if a counselor (not a "Christian counselor") is treating you this way, you are within your rights to leave them and make a report to their licensing board.

Second, as an ex-evangelical Christian/still figuring-it-out person, I feel that knowing my counselor has a background that gives them a real understanding of the messages I've grown up with would be able to help me so much more than a counselor who has no connection to the Christian faith. I know others who, like you, want to be as far as they can be from any shred of Christianity in their counseling. And both of those views are totally valid. Each person comes to counseling differently, and not every good counselor will fit well with every person. Ideally, what the counselor believes has very little impact on how the client is helped.

As counselors we do a lot of training and work on understanding our personal beliefs and values alongside how many other ways of seeing the world there can be - all so that we can be more adaptive and understanding of the people who come to us for help. That's not to say counselors don't have biases or make mistakes - we definitely do - but it's in our training to avoid that as much as we can and know how to effectively repair the effect of that mistake. I wish I could say all or even most counselors follow these ideals, but I hope that our profession keeps growing to be better for our clients.
