“In my most deliberate judgment, I am convinced that the religious observance of the Lord’s day is essentially connected with vital piety. No Sabbath, no religion, is a maxim which you may safely apply, both to individuals and to communities...The very truth is, a life of communion with God cannot be maintained without frequent exercises of devotion, considerably prolonged. And all who lead such a life do, and will, avail themselves of every season that is favourable, for the practice and cultivation of that in which they find their highest enjoyment. If, therefore, my young friends, whatever may be the practice or pretence of others, be it your care, to ‘Remember the Sabbath day, to keep it holy.’” — Ashbel Green, Lectures on the Shorter Catechism, Vol. 2 (1841), pp. 147-148
