No one gets a general amnesty for his or her wrongdoing. We must turn to Christ as individuals. Only then will guilt-stricken consciences find peace. Religions vary according to their founders, beliefs and practices. What's more, there's a difference between religion and Christianity.
Religion puts emphasis on external ceremonies.
For example, some devout people travel to Co-Mayo, Southern Ireland and do penance for their sins. Our Fathers, Seven Hail Marys and one creed. This is religion, people doing things to please God. Christianity differs because it emphasizes what God has done for us. Christianity declares that Christ died on a cross so that we might have forgiveness of sins.
