“Take this all of you and eat. This is my body which will be given up for you” / “Take this all of you and drink, this is the cup of my blood, the blood of the new and everlasting covenant, this cup will be shed for you and for all."Now of course Heaven is exclusionary since we can't hold a belief in universal salvation. But it is still who humans who long for exclusion and caste; when Jesus ate with sinners He was greatly criticized. In "The Power of the Cross", Michael Dubruiel mentions the parable of the Prodigal Son:
Jesus tells this parable when he is in the process of being judged as someone who consorts with sinners. The "punch line" of the parable hits home for all of us prodigals: Those who are most likely to come to their senses are those who have experienced the emptiness of a life apart from God. The elder sons really don't see any readon to party; they haven't come to their senses yet.
Who is the greatest sinner in the parable of the Prodigal Son? Could it be the older brother, who is angry that his ungrateful little brother had come home? Often we resent this; we identify more with the elder brother than with the younger. In fact, when I've spoken on this parable it has often angered someone: Someone in their family, like the Prodigal Son, has taken the family's money, only to come back penniless and in search of more.
Ironcally, some Scripture scholars think that in the parable of the Prodigal Son, Jesus is the son who takes the inheritance of the Father - his divine mercy and love - and squanders it on sinners! In the end, the Father is pleased. Once you've heard this way of looking at the parable, it's hard to see it any other way.
Yes, God's mercy is great; however, to experience it fully always involves a bit of crucifixion on our part. Our natural human way of looking at things is invariably fallible and has to die.
