Not sure what year that is from (and I doubt anyone current JWs would use something so old) but I just found this on JW.borg:
https://www.jw.org/en/jehovahs-witnesses/faq/jw-celebrate-holidays/
Opening paragraph: (see sentence in BOLD)
How do Jehovah’s Witnesses determine whether a holiday is acceptable?
Before deciding whether to celebrate a particular holiday, Jehovah’s Witnesses consult the Bible. Some holidays and celebrations clearly violate Bible principles. When that is the case, Jehovah’s Witnesses do not participate. Regarding other holidays, each Witness makes his or her own choice, striving “to maintain a clear conscience before God and men.”—Acts 24:16.
so reading through I didn't see anything about Mothers day AT ALL.....based on this could a JW based on his own conscience (and this article) celebrate mother's day guilt free??
Thoughts??
