There is no difference in meaning, they might be used in different situations though.

It's an interesting problem.

Could you describe these different situations or where I can read about them?

I'm sorry for intruding.

Thank you for your help.

In most situations, meeting friends or family members, we would say "Merry Christmas". If we are writing Christmas greetings to someone, we might write, "I wish you a Merry Christmas..."
