116 But although, venerable brethren, devotion to the Sacred Heart of Jesus has everywhere brought forth fruits of salvation for the Christian life, all are aware that the Church militant on earth -and especially civil society - has not yet attained in a real sense to its essential perfection which would correspond to the prayers and desires of Jesus Christ, the Mystical Spouse of the Church and Redeemer of the human race. Not a few children of the Church mar, by their too many sins and imperfections, the beauty of this Mother's features which they reflect in themselves. Not all Christians are distinguished by that holiness of behavior to which God calls them; not all sinners have returned to the Father ' s house, which they unfortunately abandoned, that they may be clothed once again with the "first robe"(115) and worthily receive on their finger the ring, the pledge of loyalty to the spouse of their soul; not all the heathen peoples have yet been gathered into the membership of the Mystical Body of Christ.
