Hi, Celtic: Non-attendance at Easter Mass would go against the Fourth Precept of the Church i.e. attendance and participation at Mass on Holy Days of Obligation. I do not think non-attendance would suffice for excommunication, unless of course conduct is heretical or perhaps grave in that manner. I also do not think that the Church would impose a moral and spiritual burden on the faithful if one's circumstances make it impossible to attend Easter Mass. Perhaps, whereas before, the sick and infirm would obviously be excused, geographical locations, amongst a few others, can also be treated as posing impossibility. There are fewer priests now and in some areas, it would take to hike miles to just get to the closest Church.
