As well as paying tribute to the late Queen, he is also expected to reference the 'desperate struggles of hospital wards' as well as those people who make perilous journeys in small boats, when he delivers his annual message.
Mr Welby is set to tell those listening that despite war and conflicts around the world and financial pressures on people closer to home, there is"unconquerable hope" in the birth of Jesus Christ.
In his first Christmas message since the death of Queen Elizabeth II, Mr Welby will praise the example set by the late monarch, who"in obedience to the Christ-child lived a life of service and put her interest after those of the people she served". The archbishop visited a church-run food bank in Canterbury in recent days and is expected to express concern for those struggling in a cost of living crisis.
He will say:"In Jesus Christ, God reaches out to each one of us here; to those who like his family have no resources, into the dark cells of prisons, into the desperate struggles of hospital wards, to those on small boats, to the despairing, and even to the condemned and the wicked, and says: 'Take me into your heart and life, let me set you free from the darkness that surrounds and fills you, for I too have been there.
