In the English church, and in some parishes in Canada, the Fourth Sunday of Lent is also called Mothering Sunday, from the Epistle reading for the Day where we read, “Jerusalem which is above is free; which is the mother of us all.” [Galatians 4.26 - Book of Common Prayer, page 147]
People would visit the church in which they were baptized. Parishioners would visit the “mother” church of a multi-point parish.
The customary school break in the spring allowed students to visit home as well. Servants being allowed the Sunday off were able to pay a visit to their mothers reinforcing the theme of the Day.
A tradition in many homes and parishes is the serving of Simnel Cake on Mothering Sunday.
