Q: I have understood the Easter duty as being the necessity of receiving the sacrament of reconciliation during the Easter season. For years it was taught to be the necessity of receiving Communion during the same time period. In the United States I have read where the time period begins with Lent and ends with Trinity Sunday. How correct am I?
A: Please check with a canon lawyer for a correct interpretation, but look at canon 920.
As I understand this, communion is required during Easter Time—from Easter Sunday through Pentecost. Confession is required for those whose mortal sin keeps them from receiving communion.
