Context

“Now every man is not bound to imperil his own body for his neighbor's safety: this belongs to the perfect, according to John 15:13: "Greater love than this no man hath, that a man lay down his life for his friends." Therefore a man is not bound, out of charity, to love his neighbor more than his own body. On the contrary, Augustine says (De Doctr. Christ. i, 27) that "we ought to love our neighbor more than our own body." I answer that, Out of charity we ought to love more that which has more fully the reason for being loved out of charity, as stated above” source
