14 “You shall not commit adultery. Exodus 20:14WEB
This passage contains a negative command, directed toward Israel: "You shall not commit adultery".
This command fits with other commands related to Loving one's neighbor.
This command contributes to an understanding of the laws related to Adultery
This command finds its ultimate fulfillment in heaven, where, as Jesus said, 25 For when they will rise from the dead, they neither marry nor are given in marriage, but are like angels in heaven. Mark 12:25WEB. Being not married nor given in marriage, adultery will be impossible.
Furthermore, inasmuch as marriage is a reflection of the relationship between God and the Church, we know that Israel committed adultery against God (see Jeremiah 3:2), and that the Church is the Bride of Christ (See John 3:29, Mark 2:19). In this sense, the command finds its fulfillment in the same way that the commands in Exodus 20:3 and Exodus 20:4-6 are fulfilled in ultimate.
At this time, this command has abiding relevance to us, and continues to be obligatory.
This is the seventh command in what are called the Ten Commandments.
