3. To this divine worship, founded within the heart, and proceeding from faith, love, and humility, St. Paul powerfully exhorts us in Rom. 13:8-10. His admonition contains in it both the praise of Christian love, and the perpetual duty in which we stand engaged to our neighbor, and without which it is impossible to serve God aright. For truly there is no other way of serving God, except by that which he himself works in our hearts: so that to serve God, is nothing else but to serve our neighbor, and to do him all the offices of Christian love and humanity which we are able to perform. 4. The apostle calls love a summary of all virtues, and the “fulfilling of the law.” Rom. 13:10. Not that we are able by any acts of charity, to fulfil perfectly the divine law, or that consequently we can merit eternal life thereby; (which cannot possibly be, except our love were complete in every respect, and arrived to a consummate perfection): but the apostle desires to suggest thereby the wonderful excellency of this virtue, and to incline us, at the same time, to an unfeigned love. As to our righteousness, it is not grounded on any work of ours, but only on the merits of Christ applied to us by faith. 5. From this righteousness of Christ, apprehended by faith, springs love to our neighbor, together with the whole train of Christian virtues, called by the apostle “fruits of righteousness, which are to the glory and praise of God.” Phil. 1:11. But since the dignity of this virtue is so very eminent, it will be proper to set forth further motives by which the practice of it may be endeared to us.
