"In our view, Scripture seems consistently to refer to marriage as a covenant between a man and a woman, leading us to uphold the heterosexual union as God's original intended design for humankind…. Yet, we support our gay friends and family member who choose to commit themselves to lifelong, monogamous marital union in the belief that this is God's best for them. They do so in the belief that it reflects an authentic sexuality that is congruent with themselves and with Scripture, and seek to serve God and each other in a faithful, committed, covenant relationship before God." (page 84)

"Masturbation and lust distinction. The Bible is silent on masturbation, but not silent on sexual sin. The realities of sexual sin, such as the use of internet pornography, which becomes a compulsion, is a problem. Jesus addresses the issue of lust in Matthew 5:27-28: "You have heard that it as said 'You shall not commit adultery.' But I say you you that everyone who looks at a woman lustfully has already committed adultery with her in his heart. (RSV) Jesus does not condemn being attracted, sexually aroused, or even having sexual thoughts about a person. Rather, Jesus is warning that lusting after a certain person sets one on a potential path of committing adultery. Fantasy can be used to increase responsiveness in the relationship, or it can become a substitute for unmet needs.
Lust need not be equated with fantasy. Fantasy allows us to imagine God-given dreams and goals." (page 126)

"Second, it is important to respect our Christian liberties when viewing erotica. Once again we refer to the 1 Corinthians 6:12 passage about Christian liberties: 'I can do anything I want to if Christ has not said no' (LB). Although this principle may feel uncomfortable to some, it is important not to judge another's actions where Scripture's teachings are not absolute. In addition, honest discernment is helping in discriminating between the things that direct us in God's way, and those that do not.
Third, the effects of erotica are dependent on the context of one's situation. Paul continues in 1 Corinthians 6:12, 'But some of these things aren't good for me. Even if I am allowed to do them, I'll refuse to [do so] if I think they might get such a grip on me that I can't easily stop when I want to' (LB). Paul's use of but qualifies freedom in Christ… Paul is not saying that 'these things' are not good, but that they are not good for him.
For the Christian, 'these things' may include erotic material. It is a strong possibility that Paul was specifically addressing the issue of erotica. In the following verse, Paul writes, "But it is not true that the body is for lust" (1 Cor 6:13 NEB). According to Paul, certain types of erotica may not be wrong in and of themselves. However, the context of the erotica can determine whether erotic material is healthy or unhealthy." (page 235)
