Romans 14:1-13 — This passage is speaking of Jews who were observing the Old Testament Jewish holy days/festivals and dietary laws even though they were now believers in Christ; but they were also judging their Gentile brothers-in-the-Lord who did not observe the Jewish customs. Likewise, the Gentile Christians were judging their Jewish brothers who were seemingly caught-up in ceremonial law. Paul was thusly saying, “To you Gentile Christians — leave the Jewish Christians alone, because they are not violating any Scriptural commands by their actions (i.e., it’s a “disputable” matter [doubtful or gray area] and not a moral issue). To you Jewish Christians — it’s okay for you to observe the Jewish festivals and dietary laws because they were given by God in the Old Testament, and thereby, are considered to be previously approved worship forms, but don’t judge your Gentile brothers, because there is no Biblical command for either of you to continue to observe these things.” (Actually, it wasn’t “okay” [see IV.C. below], but Paul allowed it as an act of an immature/weaker brother [see II.G. above].) If a moral issue is involved (i.e., a practice that is covered in Scripture), then this passage and its application to Christian liberty (i.e., the freedom to engage in practices not prohibited by Scripture) would obviously not apply. And as brought out earlier in this report, the celebration of Christmas appears to be such a moral issue, because its celebration is not only not from God, but is from ancient paganism itself!
1 Corinthians 8:4-13 — The Gentile Christians, who had been raised in an idolatrous system, were having a problem with their Jewish brothers who were eating meat that had been sacrificed to idols. (Apparently, this was the only “healthy” meat available.) Similar to the Romans 14 passage above, Paul says that eating meat that had been sacrificed to idols is not a moral issue, and thereby, is not prohibited. However, Paul does not say that it is okay to go into the pagan temple itself; in fact, in other passages (1 Cor 10:14, 18-21), Paul specifically prohibits getting involved with the pagan feasts. In other words, it’s not a moral issue to partake in the byproducts of a pagan religious system (note, however, that there is no indication here that the Jewish Christians were using the “idol meat” as part of their worship), but it is not okay to partake in the religious system itself (because the corrupt character of the participants would be harmful for believers). Rather, we must be separate from the worldly system (2 Cor 6:14-7:1). Therefore, when items (byproducts) associated with a pagan religious system not only develop religious associations of their own, but have been integrated into what would otherwise be true Christian worship (as the celebration of Christmas has clearly become in our culture), then we should pull away from them so that there is no confusion over our allegiances.
Galatians 4:9-10;Colossians 2:16-17 — Both these passages of Scripture refer to the Jewish holy days under Old Testament law. If Christians were not even to observe the Old Testament holy days — days that did have divine sanction, for a time — they certainly don’t have the liberty to observe pagan holy days!
James 4:11 — James is saying that Christians may only judge a brother on matters determined in God’s Word (i.e., moral issues). If a matter is not covered in the Word, then these are matters of Christian liberty (á la Rom. 14:1-13 and 1 Cor 8:4-13), and he who judges in these areas of Christian liberty is, in effect, judging and condemning the Word of God as being an imperfect standard to which the judge, thereby, refuses to submit. On the other hand, since we have clear Scriptural precept that condemns the things that go on around December 25th in the name of Christ, the celebration of Christmas does not appear to be a matter of liberty, but one of moral conduct.
