86. Some commandments of the Mosaic Law must be kept both physically and spiritually, others only spiritually. For example, 'You shall not commit adultery, you shall not kill, you shall not steal' (Exod. 20: 13-15) and so on must be kept both physically and spiritually (the spiritual observance is threefold, as explained below). To be circumcised (cf Lev. 12: 3), to keep the Sabbath (cf Exod. 31:13), and to slaughter the lamb and eat unleavened bread with bitter herbs (cf Exod. 12:8; 23:15) and similar injunctions are to be kept only spiritually.
