40. And so let us always give the thanks that are due for the institution of the sacraments and be mindful of the oath of fidelity, whereby we are bound in receiving the sacraments. And like spiritual soldiers let us wage war constantly against Satan, our flesh and the world. In this warfare, wherein we are assisted by these aids, may we at last reach that point where, when the signs have ceased, we shall behold the very thing itself with blessed vision and possess it with everlasting enjoyment, when every war will have ended, and we shall live in everlasting peace with the prince of peace, Jesus Christ. To him be the glory forever.
