Jesus returns to instructing His Disciples about how they are to conduct themselves as His followers. The emphasis in this passage is specifically about their responsibility to help each other walk and grow in holiness, purity, and the exercise of faith. There are very real threats to the life faith - temptations that can not only lead us into sin, but can shipwreck our faith. Woe to the person, who is the result of another turning away from the faith. This pressure exists from outside the Church, but we must also be on our guard against false teaching within the Church - teaching that can turn a person away from true faith.
