"Now you are the body of Christ and individually members of it." From this Sunday's reading in I Corinthians 12.
"The mediator between God and humanity, the man Christ Jesus, freely paid for us what he did not owe. For our sakes he offered the death of his flesh, which he owed no one, in order to set us free from the the death of our souls, which was our due... We have been truly set free from subjection to sin because we are united to him who is truly free. It is certain, and we cannot deny it: we have to confess that the ruler of this world has much against us. But even so, at the time of our death he will be unable to seize us because we have become members of one on whom he has no claim." St. Gregory the Great
