29 This most tender, forgiving and patient love of God, though it deems unworthy the people of Israel as they add sin to sin, nevertheless at no time casts them off entirely. And though it seems strong and exalted indeed, yet it was only an advance symbol of that burning charity which mankind' s promised Redeemer, from His most loving Heart, was destined to open to all and which was to be the type of His love for us and the foundation of the new covenant.
