I can't believe there are Catholic clergy who would consider the composition of the communion wafer more important than the act of Communion itself! If Jesus is part of the Trinity and therefore a part of God, that means he is omnipotent, yes? If he is omnipotent, then he can bloody well be symbolized in a communion wafer made of rice as easily as he can one made of wheat.
According to Christian belief, we are all God's children and therefore all entitled to participate in the breaking of bread to symbolize the sacrifice Christianity teaches that Christ made for all of us. It is doctrinally absurd to exclude some, ostensibly, of Christ's people by claiming that only communion wafers made from wheat are valid.
This is going to be Benedict's first test as Pope, and the world will be watching him, to see if dogma will win out over compassion. I hope he passes the test. I'd like to think he will.
