Certainly it is sad when family becomes hostile when one out of conviction distanced themselves from Christmas.
However, I have known people who bring it on themselves and wonder why their family acts that way.
For example the issue of homeschooling.
About 4 years ago we had several big families in our Church, who were involved in an organization called 'Vision Forum'.
Unfortunately they were very militant on the issue of homeschooling and when others didn't homeschool their children. They became very vocal that anyone who did not homeschool their children was in sin.
Eventually our elders had to become involved and more than 20 people left the Church that were in that organization left the Church.
Understand here; I am not against homeschooling. In fact it is probably the best avenue for teaching children. However, these people were very legalistic in their approach to that topic.
When it comes to Christnas we should act on our convictions, but we must steer clear of legalism.
