Have right belief ("ortho-doxy") and good works! Whoever has these two has certain hope of eternal salvation. As Scripture says: "You see then that a man is justified by works, and not by faith alone." (James 2:24) A little later in the same place: "For as the body without the spirit is dead, so faith without works is dead" (James 2:26). Elsewhere St. Paul says the same thing: "…having faith and a good conscience, which some have rejected, concerning the faith have suffered shipwreck" (1 Tim. 1: 19).
