In the Catholic Faith, holy days of obligation are days that require us to attend Mass. Sunday is described as the “primordial holy day of obligation,” according to the Code of Canon Law, hence we are expected to go to church on this day but there are other special days as well.
Easter is a beautiful celebration of the resurrection of Jesus Christ. In the Gospels, Jesus Christ died for the sins of humankind. He rose three days after his crucifixion which is a miraculous and meaningful event for Christians.
