I recently saw this:
A person who is*** conscious of grave sin is not to celebrate Mass*** or receive the body of the Lord without previous sacramental confession unless there is a grave reason and there is no opportunity to confess; in this case the person is to remember the obligation to make an act of perfect contrition, which includes the resolution of confessing as soon as possible. (CIC 916)
Does this mean that if we are aware of a mortal sin on our souls, we should not attend mass? I thought that the Sunday obligation was there, mortal sin or not? I understand not partaking of the Eucharist, but now I’m wondering about mass attendance.
