Will anyone from the pro-gay position show any scriptures supporting their view that a "marriage" can be a same-gender coupling?
David and Jonathan doesn't support it, Ruth and Naomi doesn't support it and the Roman and his ill servant doesn't support it.
So, where is the biblical support for altering marriage in the Christian Church as the world and its secular views wants redefine it?
1 Corinthians.
In Chapter 10, verse 13, Paul writes:
There hath no temptation taken you but such as is common to man: but God [is] faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear [it].
God promises to always provide "a way to escape" from any temptation to sin.
In Chapter 7, he writes:
Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman. Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband. Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband. The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife. Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
But I speak this by permission, and not of commandment. For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that. I say therefore to the unmarried and widows, It is good for them if they abide even as I. But if they cannot contain, let them marry: for it is better to marry than to burn.
1 Corinthians 7:1-9
So, Paul suggests that one of the purposes of marriage is to provide a "way to escape" from sexual temptations. As with all "ways of escape" the sinner is free to ignore it and sin anyway. Paul says that in this case, there is a partner helping you to escape the temptation, and that it is each partner's obligation to provide all of the "escape" the other needs, so that your "incontinency" in fulfilling what are sometimes called your "marital duties" does not lead to the very temptation you are supposed to be helping your partner to escape from.
He also says that he has been given a gift -- a different "way to escape," and that he wishes everyone had the same gift, but they don't. Different people are given different gifts, according to the parts they have been chosen to play in the outworking of God's plan. (He goes into more detail on this in chapter 12.) He advises everyone that does not have the gift and who is not yet married to marry rather than burn.
But what do you tell a gay man? You tell him he must remain celibate or marry a woman. As a lifelong celibate, I can tell you that celibacy is not easy. Paul had a reason for saying that those who are not called to a life of celibacy -- and given the gift to live that life should marry. Even with the gift for celibacy it is a constant struggle to avoid sexual temptation. Without the gift it would be impossible.
Telling someone who does not have the gift for it that he must face a lifetime of celibacy is handing him over to temptation just as surely -- no even more surely -- than a spouse that does not fulfill his/her "marital duties."
And for many gay men, telling them to marry a woman is no better. It is not a woman's body that tempts them. You have recently mentioned that you struggle with the temptation of inappropriate contentography. I would imagine that your struggle is not confined to the pages of smutty magazines and videos, though, and that the way a woman fills out a swimsuit is just as distracting to you, and results in you looking at her with less than noble thoughts in your head. I assume, though, that the thought of the shape of a male body does not tempt you in the same way.
Imagine for a moment a society in which the "gay indoctrination" that you go on about has won and then take it further. Same-sex marriage is not only legal, it is the only form of marriage recognized. Would you be able to marry another man? Even if you could, since the male body does not tempt you, but the female body is nothing but temptation, how could a husband fulfill your needs and help you to escape the temptations of the female body? Maybe now you can understand why marriage to a woman would not provide a "way to escape" for a gay man with no sexual interest in women.
So God has promised a "way to escape" from every temptation, but you deny the only viable "way to escape" that gays have. Holding out false solutions.
Unless you are willing to live a life of celibacy whether or not you have been called to it, or gifted for it, do not call for imposing it on others. If you can't imagine marriage to someone whose sexual attributes are the opposite to your temptaions fulfilling you so that you can escape those temptation, you can't expect others to not only imagine it but live by it.
So then, if same-sex marriage is not implied in Chapter 7, then 10:13 is a lie. I don't believe that 10:13 is a lie, do you?
