I wouldn’t be offended or consider saying anything to anyone who included this in their out of office message, but even as someone who is in a religion that forbids use of electronics on most holidays, I still think this message is 1) TMI; 2) doesn’t convey what it needs to convey unless you are explaining that you don’t use electronics during holidays, in which case you can just include that you won’t be checking email without including the religious explanation; 3) would come across to me as inclusion of personal information I don’t need, which would therefore strike an unprofessional tone,and I wouldn’t understand why you felt the need to include that info. How about “I’m out of the office without access to internet or email until (date). If you need assistance before this date, please contact…” Like I said, I think your colleagues are overreacting, but in general I would advise to leave all personal information out of your auto-reply — vacation, medical leave, religious observance, etc. — people do not need to know why you are out.
The Christmas holiday wishes for the office are sent to inform and wish the employees for Christmas and Christmas holidays. The wishes are sent during the Christmas holidays when the staff leaves for Christmas vacations with friends and family. One can send the wishes through cards, text messages and mails for the staff customers

My biggest pet peeve is the opposite – people who NEVER turn on their OOO! I’m not saying for a day but when they’re out for an extended period of time and I’m reaching out to get a deliverable.
