Westminster Larger Catechism
Q. 39. Why was it requisite that the Mediator should be man?
A. It was requisite that the Mediator should be man, that he might advance our nature,[152] perform obedience to the law,[153] suffer and make intercession for us in our nature,[154] have a fellow-feeling of our infirmities;[155] that we might receive the adoption of sons,[156] and have comfort and access with boldness unto the throne of grace.[157]
