Today goes under various names.
From the first words of the Entrance antiphon it is known as ‘Quasimodo’: “Like new-born infants, you must long for the pure spiritual milk, that in him you may grow to salvation, alleluia” 1 Peter 2:2.
These words address the newly baptised, who are on a ‘learning curve’ as disciples and must be given milk at first rather than meat.
In ancient times it was the custom to give them the symbolic food of milk and honey.
The term ‘Low Sunday’, or in Latin ‘Dominica in Albis’ likewise refers to the completion of the Easter octave and the laying aside of the white robes of baptism.
More recently it has become known as the Feast of Divine Mercy in response to Our Lord’s request made to St Faustina Kowalska.
This focuses on the theme of forgiveness contained in the Gospel where Jesus appears a second time in the upper room and grants to the Apostles the power to forgive sins.
