Why Jehovah's Witnesses Celebrate Wedding Anniversaries but not Birthday Anniversaries
This is because there are no pagan origins connected to marriage or wedding rings. Marriage was divinely instituted by the "one true God"...Jehovah. (Genesis 2:18-24; Matthew 19:4-6; John 17:3)
And unlike the mentioned examples of birthday celebrations, the Bible does not put marriage in a bad light. Jesus himself both attended a marriage celebration and contributed to the pleasure of the occasion.—John 2:1-11.
