benefit sick by the activity of healing.
Correct, unless the "healing" is by methods he opposes, like stem cell use (and research), or artificial ways to keep a person live while the healing is going on (such as external hearts or lung machines). Honestly, it is hard to get a read on him, he mixes "naturalistic" and "humanistic" and "biblical" philosophy, and he changes his tune over time. George W. Bush liked his songs, and formed a so called "stem cell committee" in <honor> of him.
I haven't read Leon Kass, but most doctors would choose to benefit the sick by healing.
