Argumentum ad antiquitatem, stop it already!
Someone once said to me that we do things all the time that are pagan in nature such as Christmas, wedding traditions, etc. so there is nothing inherently wrong with these just because they have pagan origins.
Because we have been doing somethings for any period of time does not logically and, more importantly, Biblically make them right.
If we prove all things as the Bible tells us to do then we would be weeding out more and more of these compromises.
Prove all things; hold fast that which is good. Abstain from all appearance of evil. 1 Thessalonians 5:21-22
Christian liberty is what most people claim at this point to continue to justify their desires but Christian liberty does not give us the right to do things contrary to God's will especially if they are an abomination (unclean) to God. Our liberty is in Christ and we “GET TO” server Him through serving others.
For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another. Galatians 5:13
I have said this before but will say it again. God told us that just because we want to say something is clean or acceptable to God does not mean it is. Only God can cleanse the unclean in this sense.
Thus saith the LORD of hosts; Ask now the priests concerning the law, saying, If one bear holy flesh in the skirt of his garment, and with his skirt do touch bread, or pottage, or wine, or oil, or any meat, shall it be holy? And the priests answered and said, No. Then said Haggai, If one that is unclean by a dead body touch any of these, shall it be unclean? And the priests answered and said, It shall be unclean. Then answered Haggai, and said, So is this people, and so is this nation before me, saith the LORD; and so is every work of their hands; and that which they offer there is unclean. Haggai 2:11-14
To use tradition to justify the legitimacy of anything is a logical fallacy called argumentum ad antiquitatem or pleading to antiquity or tradition. Stop being fallacious and start proving all things as the Bible says you ought to do...
