The Christian Message, which in its origins intended to be an affirmation and culmination of Judaism, became very early diverted into a repudiation and negation of Judaism; obsolescence and abrogation of Jewish faith became conviction and doctrine; the new covenant was conceived not as a new phase or disclosure but as abolition and replacement of the ancient one; theologically thinking fashioned its terms in a spirit of antithesis to Judaism. Contrast and contradiction rather than acknowledgement of roots relatedness and indebtedness, became the perspective. Judaism a religion of law, Christianity a religion of grace; Judaism teaches a God of wrath, Christianity a God of love; Judaism a religion of slavish obedience, Christianity the conviction of free men; Judaism is particularism, Christianity is universalism; Judaism seeks work-righteousness, Christianity preaches faith-righteousness. The teaching of the old covenant a religion of fear, the gospel of the new covenant a religion of love.
