What about what Scripture says on the topic?
Knapp: The Bible has literally saved my life. I find myself between a rock and a hard place—between the conservative evangelical who uses what most people refer to as the "clobber verses" to refer to this loving relationship as an abomination, while they're eating shellfish and wearing clothes of five different fabrics, and various other Scriptures we could argue about. I'm not capable of getting into the theological argument as to whether or not we should or shouldn't allow homosexuals within our church. There's a spirit that overrides that for me, and what I've been gravitating to in Christ and why I became a Christian in the first place.
Leviticus 11:12 'Whatever in the water does not have fins and scales is abhorrent to you.
Deuteronomy 14:3 "You shall not eat any abomination.
Leviticus 19:19 'You are to keep My statutes. You shall not breed together two kinds of your cattle; you shall not sow your field with two kinds of seed, nor wear a garment upon you of two kinds of material mixed together.
Deuteronomy 22:11 "You shall not wear a material mixed of wool and linen together.
Mark 7:19 since it enters not his heart but his stomach, and is expelled?” (Thus he declared all foods clean.)The unfolding of redemption brings certain aspects of the Law to fulfillment in Christ. They were set up with a sort of time delay whereby when the fulfillment comes in Christ these aspects are no longer necessary just as a shadow passes away in the presence of the real.
9 The next day, as they were on their journey and approaching the city, Peter went up on the housetop about the sixth hour  to pray. 10 And he became hungry and wanted something to eat, but while they were preparing it, he fell into a trance 11 and saw the heavens opened and something like a great sheet descending, being let down by its four corners upon the earth. 12 In it were all kinds of animals and reptiles and birds of the air. 13 And there came a voice to him: “Rise, Peter; kill and eat.” 14 But Peter said, “By no means, Lord; for I have never eaten anything that is common or unclean.” 15 And the voice came to him again a second time, “What God has made clean, do not call common.” 16 This happened three times, and the thing was taken up at once to heaven.
Acts 10 & 11—all food is clean.
Romans 14:14 I know and am convinced in the Lord Jesus that nothing is unclean in itself; but to him who thinks anything to be unclean, to him it is unclean.Gal. 4:10 and Col. 2:16-17—we do not have to celebrate feasts.
Colossians 2:16-17 16 Therefore no one is to act as your judge in regard to food or drink or in respect to a festival or a new moon or a Sabbath day-- 17 things which are a mere shadow of what is to come; but the substance belongs to Christ.Sabbath is no more holy than any other day:
Romans 14:5-6 5 One person regards one day above another, another regards every day alike. Each person must be fully convinced in his own mind. 6 He who observes the day, observes it for the Lord, and he who eats, does so for the Lord, for he gives thanks to God; and he who eats not, for the Lord he does not eat, and gives thanks to God.Sacrifices that were once a year—are not fulfilled by the “once for all time” of Jesus’ death. In the same way ceremonial principles laid out in the OT commands are fulfilled in Christ. If the fulfillment has come we are not under the same obligation to practice them—but we do not merely throw them out. It is not just that the Christian chooses what to throw out “eeni, meeni, miney, mow”. We are not “abolishing” what was laid down… rather we are saying that Christ has ushered it to fulfillment.
