So much legalism to add to the Word which doesn't forbid believers from many things that some condemn them for.
Col 2
"16 Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. 17 These are a shadow of the things that were to come; the reality, however, is found in Christ. 18 Do not let anyone who delights in false humility and the worship of angels disqualify you for the prize. Such a person goes into great detail about what he has seen, and his unspiritual mind puffs him up with idle notions. 19 He has lost connection with the Head, from whom the whole body, supported and held together by its ligaments and sinews, grows as God causes it to grow.
20 Since you died with Christ to the basic principles of this world, why, as though you still belonged to it, do you submit to its rules: 21 “Do not handle! Do not taste! Do not touch!� 22 These are all destined to perish with use, because they are based on human commands and teachings. 23 Such regulations indeed have an appearance of wisdom, with their self-imposed worship, their false humility and their harsh treatment of the body, but they lack any value in restraining sensual indulgence."
Yes, I honor Christ in my remembrance of His birth and resurrection, regardless of the unknown dates that they actually occurred. I'm also happy to turn a dark pagan festival around and shine His Light for the world.
Paul is talking about Christians returning to the law of Moses, not pagan practices.
"anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. 17 These are a shadow of the things that were to come; the reality, however, is found in Christ"
Mixed worship was/is never accepted by God. He is merciful but consequences are quite possible. Christians are blessed at all times unless they do things to curse themselves which allows Satan to come before God's throne and demand his right to carry out the curse. Here is the example of how God sees us. It is obvious that Israel had issues even when Balaam spoke this. However God was not looking to curse but bless until they indulged in paganism. Numbers 25:1-3.
Numbers 23:19-21
New King James Version (NKJV)
19 “God
is not a man, that He should lie,
Nor a son of man, that He should repent.
Has He said, and will He not do?
Or has He spoken, and will He not make it good?
20 Behold, I have received
a command to bless;
He has blessed, and I cannot reverse it.
21 “He has not observed iniquity in Jacob,
Nor has He seen wickedness in Israel.
The Lord his God
is with him,
And the shout of a King
is among them.
Numbers 25:1-3
New King James Version (NKJV)
Israel’s Harlotry in Moab
25 Now Israel remained in Acacia Grove,[
a] and the people began to commit harlotry with the women of Moab. 2 They invited the people to the sacrifices of their gods, and the people ate and bowed down to their gods. 3 So Israel was joined to Baal of Peor, and the anger of the Lord was aroused against Israel.
Here is the NT example:
Revelation 2:14
New King James Version (NKJV)
14 But I have a few things against you, because you have there those who hold the doctrine of Balaam, who taught Balak to put a stumbling block before the children of Israel, to eat things sacrificed to idols, and to commit sexual immorality.
Please look into the history and origin of Easter. The life you save my be your own.
