Question For Pastors, And Evangelists?

My son has been researching schools to enter the ministry, but it is very expensive and he doesn’t qualify for financial aid. Recently he found a site on the internet(Universal Life Church/Monastery) that ordains you when you contact them. They sent him a bunch of stuff in the mail,including a certificate and letter of good standing. I cannot trust this because they do not declare their denomination and only say that they cover all religions. He is skeptical also but wonders if it is ok to use in the capacity of praying w/people in the hospital, ect… We do not want to be affiliated with anything that is against Christianity and we can’t get a straight answer from them about it. Is it okay for him to use those credentials to minister to people that are in the hospital or nursing homes ,ect…?
Please no non-Christian answers or bashes. We ask for Christian help because that is our faith. Thank you and God bless!
