So, the person wasn't blind. I was wrong, and I will admit to being so in this case.

BUT,

That doesn't give us a right to judge the person because of this one thing. It still seems very unChristian to me to just sit and make fun of someone because they brought their dog to church. Making fun of people is simply not Christian and not proper.

Quote
Be merciful, just as your Father also is merciful. "Do not judge, and you will not be judged. Do not condemn, and you will not be condemned. Forgive, and you will be forgiven. Give, and it will be given to you; a good measure--pressed down, shaken together, and running over--will be poured into your lap. For with the measure you use, it will be measured back to you." (Luke 6:36-38 HCSB)

Also, where in Scripture does it say we can't bring our dog to church? And where in Scripture is having a pet with you considered idolatry?
