Agnus... The evidence is the scriptures. We are speaking of the doctrine of imputed rightiousness. At the moment a person is born of the Spirit and sealed into the body of Christ, they recieve the gift of imputed rightiousness. The sinless perfection of Christ is imputed to them...as a gift. Every sin the person has ever commited, or ever will commit, is completely forgiven. This took place on the cross of course. This truth renders the Catholic and Orthodox views of.... "Hope so, think so, maybe so, if I'm good enough" ...forgiviness of sins as being complete error and nonsense.
