In the Word three terms are used to refer to bad actions: transgression, iniquity, and sin. Transgression is the least bad. It means a violation of what is true in an external context, a violation of what is right and orderly. Iniquity is next and denotes acts that violate more interior truths. Sin is the worst. It is a violation of what is holy and righteous, a violation against the Lord. Sin is the deepest kind of evil. Regarding iniquity -- to be in charity, or live a life of charity is to live a life where the acts and thoughts that have top priority are those that have within them a love for the neighbor. Sometimes our love of self, our inborn desire to put ourselves first, is stronger than our charity and we do something for ourselves at the expense of our neighbor, or even do harm to our neighbor. Such an act, if our motive is selfish, is an iniquity.

9964. 'Or when they approach the altar to minister in the holy place' means in worship representative of the Lord Himself. This is clear from the consideration that the altar was the chief representative of the Lord in respect of Divine Good, see 9714, so that 'approaching the altar' and 'ministering in the holy place' there mean worship of the Lord Himself. The worship representative of the Lord consisted chiefly in burnt offerings and sacrifices offered on the altar, 922, 923, 2180, 6905, 8680, 8936. Worship representative of the Lord in respect of Divine Good took place at the altar, and worship representative of Him in respect of Divine Truth took place in the tent of meeting. This is the reason for saying that 'going into the tent of meeting' means worship representative of all things of heaven and the Church, 9963, and 'approaching the altar' worship representative of the Lord Himself. For heaven and the Church are recipients of Divine Truth emanating from the Lord, Divine Truth emanating from the Lord being truth emanating from the good of love that is His and implanted where that good is also received, consequently where the Lord, the Source of that good, is received.
