Christians must forgive. But to qualify for forgiveness, the sinner must confess his sins, express sincere contrition and do penance. It's as plain as that!
Who are you to decide who qualifies for forgiveness and who doesn't?
I quote, from the Bible.
“And when you stand praying, if you hold anything against anyone, forgive him, so that your Father in heaven may forgive you your sins.”
“But I tell you who hear me: Love your enemies, do good to those who hate you, bless those who curse you, pray for those who mistreat you. If someone strikes you on one cheek, turn to him the other also.”
“Do not judge, and you will not be judged. Do not condemn, and you will not be condemned. Forgive, and you will be forgiven.”
Christianity does not require one to seek forgiveness in order to be forgiven.
Now, Polonius, as a self-proclaimed Catholic, how do you feel about demanding apologies when Jesus makes it clear that it isn't required?
As I said - President Walesa forgave them, like a true Catholic.
