...[O]ne really can't take her serious on this topic because homosexuality hasn't been considered a capital offense during the 2,000 years of Judeo-Christianized western civilization (there's no legal precedence for it)...
Don't take me cerealisly.
Take God seriously (Lev 20:13).
Laws come from God not man (1 Ti 1:8-10, Ac 5:29). Homosexuality is a crime punishable by death (Lev 20:13).
For ye know what commandments we gave you by the Lord Jesus [1 Thess. 4:2].
"In regard to their walk, we will find Paul giving some commandments to the Thessalonians. You will remember that the Lord Jesus also gave commandments. Some of these commandments are new commandments.
Let me say this very carefully: The Ten Commandments have no part in a sinner’s salvation, nor are they standard for Christian conduct. The purpose of the Ten Commandments is to take us by the hand, as a pedagogue would take a little child by the hand, to bring us to the Cross and say to us, “Little fellow, you need a Savior!” The Ten Commandments are like a mirror which lets us see that we are sinners. The Ten Commandments were not given to save us; they were given to show us that we are sinners and that we need a Savior. That is their purpose.
However, there are commandments for believers, and the standard for Christian conduct which they set is on a much higher plane than the Ten Commandments. In chapter 5 we will find twenty–two commandments for believers given.
Now the question naturally arises: If man could not keep the Ten Commandments, how can he keep higher commandments? The Bible makes it very clear that man was not able to keep the Ten Commandments. The nation Israel transgressed these commandments as Simon Peter confessed: “And when there had been much disputing, Peter rose up, and said unto them, Men and brethren, ye know how that a good while ago God made choice among us, that the Gentiles by my mouth should hear the word of the gospel, and believe…. Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear? But we believe that through the grace of the Lord Jesus Christ we shall be saved, even as they” (Acts 15:7, 10–11).
Now if we can’t keep the Ten Commandments, how are we to keep any higher commandments of Christian conduct? Man cannot do it himself. This can be attained only by the power of the Holy Spirit who dwells within the believer (see v. 8).
“For ye know what commandments we gave you by the Lord Jesus.” Paul has some commandments for believers. We are not lawless. We should be disciplined, and we should be in obedience to Christ. It should be a love relationship—we should be motivated by love—the Lord Jesus said, “If ye love me, keep my commandments” (John 14:15)." McGee, J. V. (1991).
