The Archbishop of Westminster is returning gradually to duties this week folowing a period of rest.
Cardinal Vincent Nichols was taken ill at Mass on Remembrance Sunday.
Writing to parishes and priests last Saturday, the Cardinal thanked everyone for their prayers for him over the previous three weeks.
He said: "I have been able to take the rest that I needed and now feel much recovered. I have been blessed to have been able to do this at such short notice.
"As Advent begins I am ready to return to duties next week, although only gradually for now. I thank so many who have graciously accepted postponements of engagements and visits to parishes. I thank especially our Auxiliary Bishops who give me such support and willing service in the Diocese.
"As we begin this lovely season of Advent, let us ask the Lord to come afresh into our hearts. May we offer him our welcome, in all the simplicity and spontaneity that his blessed birth so readily evokes in us.
"Please do keep me in your prayers as I remember you in mine."
His illness meant his evidence to the Independent Inquiry into Child Sexual Abuse was postponed.
