In several discussions regarding man's ability to 'understand' spiritual things these three concepts are thrown around almost interchangeably. I'd like to know what you all believe is the difference, if any, in these three terms: Mental Assent Understanding Acceptance Also, is it possible to have mental assent without understanding? If so, what does that look like? Explain the difference. And is it possible to understand something and not accept it? Please explain. Is understanding the same as acceptance? Thanks for your comments.
