Saying May God Bless you Recently I encounter a situation where one of my close people and I went see a patient. While  we were about to leave the place, my close person said May God Bless you. Me and my close person are both Buddhist. I asked why didn't you say May the triple gem bless you. And close person replied saying since they Christians I said God bless you. But I also observed that the patients people said May God bless you.

Does saying May God bless you comes under a wrong view or wrong speech or etc or is it okay to tell? I'm just curious to know since my close person is also a Buddhist"
Just think of the flip side of it @Akila… If the patient is a devout Buddhist.. still almost all  will say "may god bless you" at the time of leaving. Will they ever say "Namo Buddhaya" when arriving, or at the time of leaving? I doubt it. It is because very few know that we Buddhists say 'Namo Buddhaya' whenever we meet or depart. At the time when the Supreme Buddha was alive, it was the practice observed by His disciples to place both hands together in a gesture of worship and greet each other by saying ‘Namo Buddhaya’, whenever they met. Today, whenever Hindus meet one-another, they too bring their hands together and say ‘Namo Narayana’ or ‘Oh Namah Shivaya’. Some say ‘Namo Sairam’ when they enter the ashram of Sai Baba. 

But in a way it is OK to say “may god bless you" as the point of the Buddhist teachings isn't to reinforce the identity of "I am a Buddhist and this is what I believe." It's to cultivate compassion and loving kindness and purify anger and aversion from your life. Then your focus would be on "How can I compassionately reply to these people in a way that feels authentic to me?"  You need to be able to connect with the human being in front of you, and look past beliefs and value systems and connect with their humanity.

So focus less on yourself and focus more on the other. What words can you say to bring this being happiness and reduce his/her suffering? Intention is the most important factor and can often supersede other factors. If you feel that by replying "God bless you," (which is personally my own response), this person might experience a sense of comfort, ease, and happiness that would not be experienced otherwise, then there is nothing wrong in saying it.
