And this is our principal sin which will lie also upon our children. This is why our children suffer for our sins, even if they are innocent of them. We are tied to them by an invisible thread, in them is our blood, our spirit. If they weren't our children they wouldn't suffer for us. But in that case they wouldn't have been born from us.
Sin is a great evil because it causes innocent suffering.
But by the same spiritual law, through the suffering of some, the sins of others are redeemed. Translated from Blagovestnik , parish bulletin of the Holy Virgin Cathedral in San Francisco, July 1993.
