I, by myself, am not a person¹
Living here and not yet. Communion acts in opposition to individualism. For a Christian the idea that religion and spirituality are private matters, is as biblically illiterate as the goalie presuming she does not need her team. You need all the saints and they need you. That desire for perfectness is sifted out by being with others. When you see the bigger picture, you notice how small your selfie really is. You cannot truly participate unless you have a full team. Do you see the opposition to individualism when communion is taken as a family?
The Christian life is complex.
