Just as Christ was free from sin and so offered a perfect sacrifice, just as Christ was freed from corruption and so lives again forever, so we are called to lead lives of sinlessness and to reject anything that might lead us into spiritual decay. But what Paul has to say is not just concerned with individual behavior. It also reminds us that the life of each of us has its effects in all the others. As the community of believers, we are, as it were, one mass of dough, all of us kneaded together into the one life of the risen Christ. Sinfulness and corruption on the part of any of us brings with it the danger of corrupting all the rest.
Easter is a complex feast.
It marks the end of our lenten period of repentance and reform. It brings new members into the community of faith. It recalls for us the final outcome of the life and ministry of Jesus. It offers hope and reassurance to all who believe in Christ. But, at the same time, it also makes demands on us.
