But we know that the law is good, if a man use it lawfully;
This is a direct and explicit reference to the Mosaic law.
Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other thing that is contrary to sound doctrine;
1 Timothy 1:8-10 KJV
It's ironic that you focus on only one aspect of this passage rather than the most glaring transgression by most of Christianity, i.e. the 4th commandment. Why the double standard?
When this passage is fully understood, it will be seen that Paul is identifying persons who broke the ten commandments, up to commandment 9 and in the same order as they were given in Exodus 20.
THE LIST OF COMMANDMENT BREAKERS.
Lawless - Anomos(Gr.),without law,not having,knowing or acknowledging the law.Shows opposition to or contempt for the will of God.
Disobedient - Anupotaktos(Gr.),disobedient to authority(God's)
Ungodly - Asebes(Gr.),Godless,without fear or reverence to God,one who practises the opposite of what the fear of God demands.
Sinners - Hamartolos(Gr.),a heinous and habitual sinner.
The above persons do not recognize the true God and His laws but have gods of their own. They end up making images in honour of these gods and offer worship to them contrary to the commands of the true God.[See,Romans 1:18-25;Proverbs 16:27;Deuteronomy 13:13;II Corinthians 6:14-18;I Samuel 2:12;Galatians 4:8; N.B., ungodly - sons of belial]
The persons above break commandments 1 & 2
Unholy - Anosios(Gr.),opposite of holy,profane.
Profane - Bebelos(Gr.),unhallowed, opposite of sacred, permitted to be trodden.
The above persons disregard or desecrate that which is holy. They take the Lord's name in vain and pollute the Sabbath.[See,Leviticus 18:21;19:12;Matthew 12:5;Nehemiah 13:17;Isaiah 58:13;56:6]
The persons above break commandments 3 & 4.
The rest are fairly straightforward and self-explanatory.
Murderers of fathers and - Dishonour parents by killing
murderers of mothers them.
The persons above break commandment 5.
Manslayers - Kill others.
The persons above break commandment 6.
Whoremongers etc. - Commit adultery and various sexual sins.
The persons above break commandment 7.
Men stealers - Steal or kidnap men.
The persons above break commandment 8.
Liars and perjured persons - These persons lie, bear false witness.
The persons above break commandment 9.
Any other thing contrary to sound doctrine would include commandment 10,which must be transgressed before any other sin is committed.[See,James 1:14,15;I Corinthians 10:6;Matthew 15:19]
Hence Paul clearly affirms that the breaking of the ten commandment law is a sin and describes those who disregard the Sabbath as unholy and profane.In this passage, Paul states plainly that it is contrary to sound Christian doctrine, contrary to the gospel, to be unholy and profane ie. to disregard the Sabbath.[I Timothy 1:10,11]
So my thinking is the Bible says homosexuality is contrary to sound doctrine.
So it breaking the 4th commandment and the dietary laws.
So if we are to live in fellowship with God, a lifestyle of homosexuality should not be exercised. And as Christians, we shouldnt condone it...
Only if we are going to be consistent in our reasoning which precludes us from a lifestyle of Sabbath breaking, eating garbage, etc. We either learn to condone homosexuality, or we repent from our own hypocrisy.
