Depends on the context of which this is occurring and the job in question. If an atheist takes a job within an Christian context, this should be expected. After all, you are agreeing to maintain/support the views of those who hired you. By the same token, if you are hired by a secular agency that does not actively subscribe to the Christian tradition and you take it upon yourself to voice controversial views linked to the Christian tradition (which are also counter to the positions of the hiring body), you should expect consequences.
A minister, ministers in the context of the religion they minister from.
These are volunteer counselors, they are not "hired".
This is about a minister being told
not to minister according to ALL of their beliefs.
This would be the same as say me asking for a minister to come to me in the hospital, and then the hospital making my minister sign an agreement that he wont talk about parts of his beliefs even if asked, and agreeing that part of his beliefs are wrong and he will agree its wrong and not talk about them, in order to minister to me.
Seems you dont understand the issue here.
