Mystifying the New Testament

While Judaism without the appearance of Christ was a religion in mystery, we have in theology gone backwards in some areas and produced more mysteries where they were none, such as Christ's imputed righteousness or the act of redemption of all of humanity. While certainly, there are some more mysteries brought upon by revelation (such as the nature of the Trinity), we should not continue to mystify a religion only to bring up a new revelation to address the mystery that is no where itself mentioned specifically.
