Vocabulary redefined, part 2

Another example: sacrament.

Before: things in church rituals that we go through, not really sure why

After: a (the?) manner in which God's grace is given to us, usually through the bread (wafer) and the wine (grape juice) that we receive in communion and also baptism. Not limited to this, as I think it's any way that God gives us his grace; our lives can be sacraments to each other, for instance.
