Why does Christianity insist 'no forgiveness without shedding of blood' when Yehovah clearly says charity atones for sin?

Was God mistaken when he called Ezekiel Son of Man? Could Ezekiel forgive sins as Jesus claims?

Jesus illustrated forgiveness of sin caused healing. Does that no longer work in ways that could be verified?

Why do we find God disputing an automatic relationship between sin and affliction, punishing those that promote it, yet Jesus affirming an automatic relationship?
