What does it mean to believe in the sanctity of life?: Many apply the sanctity of life to issues like abortion and euthanasia, and while it definitely applies to those issues, it applies to much more. The sanctity of life should motivate us to combat all forms of evil and injustice that are perpetuated against human life. Violence, abuse, oppression, human trafficking, and many other evils are also violations of the sanctity of life.
