And, you are also being dishonest in claiming that physical circumcision was the only issue mentioned. In fact, days are mentioned.
Galatians 4:8-11 8 Formerly, when you did not know God, you were enslaved to those that by nature are not gods. 9 But now that you have come to know God, or rather to be known by God, how can you turn back again to the weak and worthless elementary principles of the world, whose slaves you want to be once more? 10 You observe days and months and seasons and years! 11 I am afraid I may have labored over you in vain.
(ESV Strong's)
You need a real bible my friend. See how your book left out the word times? Its the key word AND THE ONLY WORD your book changed. Coincidence? Rule 38.
GAL.4 [8] Howbeit then, when ye knew not God, ye did service unto them which by nature are no gods.[9] But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage? [10] YE OBSERVE DAYS, AND MONTHS,
AND TIMES, AND YEARS.[11] I am afraid of you, lest I have bestowed upon you labour in vain.
Galatians 4 says nothing about sabbaths or feast days. Its speaking of those who observe times.
DEUT.18 [9] When thou art come into the land which the LORD thy God giveth thee, thou shalt not learn to do after the abominations of those nations.[10] There shall not be found among you any one that maketh his son or his daughter to pass through the fire, or that useth divination, OR
AN OBSERVER OF TIMES, or an enchanter, or a witch,[11] Or a charmer, or a consulter with familiar spirits, or a wizard, or a necromancer.
The same thing goes on to this very day. Its speaking of the occult. Those who observe certain days by use of horoscopes?
2 CHR.33 [3] For he built again the high places which Hezekiah his father had broken down, and he reared up altars for Baalim, and made groves, and worshipped all the host of heaven, and served them.[4] Also he built altars in the house of the LORD, whereof the LORD had said, In Jerusalem shall my name be for ever.[5] And he built altars for all the host of heaven in the two courts of the house of the LORD.[6] And he caused his children to pass through the fire in the valley of the son of Hinnom: ALSO
HE OBSERVED TIMES, and used enchantments, and used witchcraft, and dealt with a familiar spirit, and with wizards: he wrought much evil in the sight of the LORD, to provoke him to anger
Enchantments, witchcraft, familiar spirits, and wizards. Its speaking of the occult. Not following sabbath days.
LEV.19 [26] Ye shall not eat any thing with the blood: neither shall ye use enchantment,
NOR OBSERVE TIMES.[27] Ye shall not round the corners of your heads, neither shalt thou mar the corners of thy beard.[28] Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD.[29] Do not prostitute thy daughter, to cause her to be a whore; lest the land fall to whoredom, and the land become full of wickedness.[30]
YE SHALL KEEP MY SABBATHS, and reverence my sanctuary: I am the LORD.
I guess this scripture says it all. You shall not observe times BUT you will keep my sabbaths.
ACTS 8 [9] But there was a certain man, called SIMON, which beforetime in the same city USED SORCERY, AND BEWITCHED THE PEOPLE of Samaria, giving out that himself was some great one: [10] To whom they all gave heed, from the least to the greatest, saying, This man is the great power of God. [11] And to him they had regard, because that of long time he had
BEWITCHED THEM WITH SORCERIES.
GALATIANS 3 [1] O foolish Galatians,
WHO HATH BEWITCHED YOU, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you?
Little more scriptural proof as to what Gal.4 is speaking of. The occult. Sorcery and the such
