He continued his speech touching on the importance of service and honouring those that serve their community.
"My wife and I were delighted when hundreds of representatives of that selfless army of people—volunteers who serve their communities in so many ways and with such distinction—were able to join us in Westminster Abbey for the Coronation earlier this year," Charles continued.
"They are an essential backbone of our society.
"Their presence meant so much to us both and emphasized the meaning of Coronation itself: above all, a call to us all to serve one another; to love and care for all.
"Service also lies at the heart of the Christmas story—the birth of Jesus who came to serve the whole world, showing us by his own example how to love our neighbour as ourselves.

"Throughout the year, my family have witnessed how people of all ages are making a difference to their communities.
"This is all the more important at a time of real hardship for many, when we need to build on existing ways to support others less fortunate than ourselves.
"Because out of God’s providence we are blessed with much, and it is incumbent on us to use this wisely. However, service to others is but one way of honouring the whole of creation which, after all, is a manifestation of the divine.
"This is a belief shared by all religions. To care for this creation is a responsibility owned by people of all faiths and of none. We care for the Earth for the sake of our children’s children."

"So on this Christmas Day my heart and my thanks go to all who are serving one another; all who are caring for our common home; and all who see and seek the good of others, not least the friend we do not yet know.
"In this way, we bring out the best in ourselves. I wish you a Christmas of ‘peace on Earth and goodwill to all’, today and always," Charles concluded.
