Original Sin is the wounded human nature resulting from the first sin of Adam and Eve that is inherited by all human beings. Baptism is necessary to wash away the stain of Original Sin, though certain consequences remain, such as a tendency to sin.
Sanctifying Grace
:
Sanctifying grace is the free gift of God’s love and life within our souls, given to us by the Holy Spirit. Sanctifying grace heals us of sin and makes us holy. We receive sanctifying grace primarily through the sacraments.
Mortal Sin
:
Mortal sin is serious sin that we choose to commit even though we know it is wrong. Mortal sin destroys our relationship with God and completely rejects His love for us.
Venial Sin
:
Venial sin is less serious sin that hurts our relationship with God, but does not destroy it.
