Ask him if he has considered Romans 14:5 carefully and without letting the WTS drive his imagination around. Do not allow him to try to spin the argument to the drinking and eating pseudo explanation because the chapter clearly applies to judging in general. At any rate? whatever rationalization he may come up with, you can always ask him if he REALLY believes the context was not addressing celebrations in general or if he is just repeating the party line.
Romans 14:1, 10 describe the issue having to do with "different beliefs and doubts" one of those being (and not limited to) culinary habits and festive days.
Hopefully he will see there is a biblical supported approach he has never considered before and will drop it. (Romans 14 always does the trick ?cause even the JWS feel the weight of guilt when they are shown to be violating a well known Christian principle even with the WTS support)
This is awesome advice as I had two JW's visit me today. We discussed birthdays. I asked them to just talk to me from the Bible ONLY regarding birthdays. They cited the two b-days mentioned in the Bible where bad things happened. I asked if it was ok to celebrate wedding anniversaries, and they said yes and showed me the scripture regarding Jesus attending a wedding feast and turned water into wine. They said that marriage is God's institution and anniversaries could be observed. I pointed out that Jesus was not attending an anniversary party, but a wedding feast.
I asked if they gave baby showers to pregnant JW mothers. Well of course they do.
So, let me get this straight, I can give an unborn baby gifts in honor of its birth, ALSO "GOD'S INSTITUTION", but never again celebrate its birthdate thereafter? They were silent, then said something about progressive learning and the light getting brighter and brighter, to which I replied, yes the light gets brighter and brighter but the truth does not get truer and truer.
Then I said, instead of us disputing whether its ok with God to celebrate brithdays or wedding anniversaries, especially when God did not see fit to give direct counsel on the matter, as with fornication, adultery, idolatry, stealing, etc . . . let's just read Romans 14:1-10
He pointed out that the person observing days was "weak in faith", to which I countered, which is a matter of opinion as the Scripture clearly states. If it is your opinion that person is weak in faith for observing certain festivals, just remember that his worship to God is just a acceptable as yours. I said in otherwords, it's your problem, it's your choice, and you should not for you to judge my relationship with god based on works. I also said that for you to insist that my relationship with God is not as strong as yours simply because I celebrate birthdays, is to take away my personal relationship with God and my accountability to Him, making it YOUR business, and now I have to stand and answer to you as the mediator that stands between me and the mediator, Jesus, the mediator of God? They left perplexed, lost and promising to "do more research" about B-days.
Stand your ground, use only the Bible and don't let him mess up your son with JW-ism.
