People have told me that the families of illegitimate children are cursed with sin. Is that the Church's stand?
No, God loves each person without reservation. God does not love children born within wedlock more than children born out of wedlock. We are all precious in God's eyes. Jews, Christians and Muslims today believe that God holds individuals accountable for their actions. Even though God extends neither reward nor punishment from one generation to another, humans often do. If people insist on talking about a curse in these situations, they are describing human actions, not God's.
