I have to wonder why any visit a chaplain makes would not be spiritual? Perhaps that is defined to the narrative exchanged. I find that if I work with a patient whose core value is a passion for horses/animals, if I support their core value, why is that not tending to their spirit? I cannot define spirit as religion in a world where organized religion seems to impart so much pain/suffering/judgment. I feel like grace, self-care, building trust where trust has been low with others, empowerment, and a host of other spiritual values makes the visit spiritual care. As you said sometimes the building of trust is tending to the spirit.
