Wishing Non-Muslims On Their Festivals
In Christmas, we can participate and greet with another perspective which is ours that it is the birthday of the prophet Christ, which is well known, but greeting or participating festivals to celebrate a god and for that we have no other perspective, is involving ourselves in the celebration of Shirk. and yes you second point is correct that whatever the origin is, the present form of a celebration determines its status for us.
yeah. Good point. Bdw I was not talking about participating in their rituals but Can I attain those places in the perspective of showing brotherhood and also if they invite me in a lunch or in a dinner on that festive day.
Since these things are not the essential part of the festivals so a Muslim can join them
