It's just strange that a couple of years ago my wife told me that my that my own sister and husband wanted to involve her in their open marriage. It was at that point that I told my sister that I wanted nothing further to do with her and that she was no longer welcome in my house. I had also found out some things that were going on in my family and what her husband had been doing with my mother who was in her late 70s at the time. I can tell you I was truly disgusted with all of everything that was going on.
If it was making me feel so sick what must it make God feel.
Let marriage be held in honor among all, and let the marriage bed be undefiled, for God will judge the sexually immoral and adulterous.
1st Corinthians 6:13
The Sixth Commandment
- Adultery is the sexual union of a man and woman where at least one is married to someone else. It is for this reason that the Church considers it a greater sin than fornication. Kreeft states, "The adulterer sins against his spouse, his society, and his children as well as his own body and soul."

The ninth and tenth commandments deal with coveting, which is an interior disposition not a physical act. The Catechism distinguishes between covetousness of the flesh (improper sexual desire) and covetousness for another's worldly goods. The ninth commandment deals with the former and the tenth the latter.
Jesus emphasized the need for pure thoughts as well as actions, and stated, "Everyone who looks at a woman lustfully has already committed adultery with her in his heart" (Matthew 5:28). The Catechism states that, with the help of God's grace, men and women are required to overcome lust and bodily desires "for sinful relationships with another person's spouse." In Theology of the Body, a series of lectures given by Pope John Paul II, Jesus' statement in Matthew 5:28 is interpreted that one can commit adultery in the heart not only with another's spouse, but also with his/her own spouse if one looks at him/her lustfully or treats him/her "only as an object to satisfy instinct".
Purity of heart is suggested as the necessary quality needed to accomplish this task; common Catholic prayers and hymns include a request for this virtue. The Church identifies gifts of God that help a person maintain purity:
- Chastity, which enables people to love others with upright and undivided hearts.
- Purity of intention, which seeks to fulfill God's will in everything, knowing that it alone will lead to the true end of man.
- Purity of vision, "external and internal", disciplining the thoughts and imagination to reject those that are impure.
- Prayer that recognizes the power of God to grant a person the ability to overcome sexual desires.
- Modesty, of the feelings as well as the body is discreet in choice of words and clothing.
Jesus stated, "Blessed are the clean of heart, for they shall see God." This purity of heart, which the ninth commandment introduces, is the "precondition of the vision of God" and allows the person to see situations and people as God sees. The Catechism teaches that "there is a connection between purity of heart, of body and of faith."
