I imagine we'd all support donating blood as an act of compassion and charity toward the sick and agree (along with the Church) that the selling or trafficking of human body parts is immoral as a degredation to the infinite worth of our bodies as temples of the Lord.
I'm considering donating plasma (the liquid part of the blood is separated from the blood cells, which are returned to the donor's body), for which donors are usually paid. This compenation is legal because it's identified as for the donor's time (a couple hours) and mild discomfort--not for the plasma itself. To me, the distinction is a bit murky. If I go ahead and do this, would it be morally preferable or even obligatory to decline the compensation?
Thanks for your input!
