A religious person acting upon a guide as perceived by atheists/ opponents to that guide would most certainly be acting immorally 
Humanism as I understand it is selfishly human centred, and would be against Christian morals. Humanism can be the pursuit of personal pleasure to the exclusion of other humans. Certainly non humans and environmental concerns, for example. Otherwise, secular humanism is pretty much in line and mimics Christian values. It all sounds good although I find its proponents have no grounding and can quickly switch to extreme selfishness because they have no loyalty to humanism.
