ترجمه - انگلیسی-یونانی - Wishing you all the joys of Christmas

I took the liberty of translating the names into Greek too - I wasn't sure about James - I made him Ιάκωβος. Also, the first two words are used for more than one person or a formal greeting, so if it's just one person and informal, you should replace that with "Σου" and "εύχομαι" if the wishing is from one person.
