Exodus 20:16 You shall not bear false witness against your neighbor.
Proverbs 3:29 Devise not evil against your neighbor, seeing he dwells securely by you.
Matthew 7:12 Therefore all things whatever you would that men should do to you, do you even so to them: for this is the law and the prophets.
Mark 12:31 And the second is like, namely this, You shall love your neighbor as yourself. There is none other commandment greater than these.
Romans 13:10 Love works no ill to his neighbor: therefore love is the fulfilling of the law.
Romans 15:2 Let every one of us please his neighbor for his good to edification.
Galatians 5:14 For all the law is fulfilled in one word, even in this; You shall love your neighbor as yourself.
Galatians 6:10 As we have therefore opportunity, let us do good to all men, especially to them who are of the household of faith.
James 2:8 If you fulfill the royal law according to the scripture, You shall love your neighbor as yourself, you do well:
So, therefore as Christians we are called to not only treat others kindly, but also, to edify them when they stray. IMHO, many do fall short, and people and business does commercialize Christmas more than many like to see. However, if that is your reason to back a display that not only is put up explicitly to offend, but to spread cynicism then that to me signifies a problem within those that would do that. Much of the holiday is a time that most people try to put differences aside and even if for a day, come together as family....
I asked why the Satanists would want to do such a divisive thing during this holiday, and to date have gotten NO good answer on that, so I must conclude that it is just a childish way of antagonism which is just sad.
