The Roman Catholic translation, The New American Bible, in its “Glossary of Biblical Theology Terms” (pp. 27, 28), says: “In the New Testament, to ‘save one’s soul’ (Mk 8:35) does not mean to save some ‘spiritual’ part of man, as opposed to his ‘body’ (in the Platonic sense) but the whole person with emphasis on the fact that the person is living, desiring, loving and willing, etc., in addition to being concrete and physical.”—Edition published by P. J. Kenedy & Sons, New York, 1970.
... What, really, would a man give in exchange for his soul?” (Mr 8:35-37)
