2. My Lords and brethren most beloved, we ought not so far to deviate from truth, or to be of such varying and wandering minds, as to the obligation of this celebration having been imposed upon all Christians: since our Lord Himself selected the day to celebrate it upon, which agreed with the method of the true observance. For it is written: _Then came the day when the Passover must be killed. And He sent Peter and John, saying, Go and prepare us the Passover that we may eat. And they said unto Him, Where wilt Thou that we prepare? And He said unto them, Behold when ye are entered into the city, there shall a man meet you, bearing a pitcher of water: follow him into the house where he entereth in. And ye shall say unto the goodman of the house, the Master saith unto thee, Where is the guest-chamber, where I shall eat the Passover with My disciples? And he shall shew you a large upper room, there make ready._ Sidenote: Gal. iv. 10, 11. 3. We observe then that we ought not to go down to places in the earth, but to seek _a large upper room furnished_, for us to celebrate the Lord’s Passover. For we ought to wash our senses, so to speak, with the spiritual water of the everlasting fountain, and maintain the rule of the devout celebration, and not follow common notions and go in quest of days according to the moon, whereas the Apostle says, _Ye observe days, and months, and times, and years. I am afraid of you, lest I have bestowed upon you labour in vain_. For it is sure to be injurious[128]. Sidenote: Ps. cxviii. 24. Sidenote: Ib. lxxxix. 36, 37. 4. But it is one thing to observe them after the heathen fashion, so as to decide on what day of the moon you are to attempt anything, for instance, that you should avoid the fifth[129] and begin no work upon it, and to recommend different points in the moon’s course for commencing employments, or to avoid certain days, as many are in the habit of avoiding days called ‘following’[130] or the Egyptian days: it is another thing to turn the observance of a religious mind to the day of which it is written, _This is the day which the Lord hath made_. For although it is written that the Lord’s Passover ought to be celebrated on the fourteenth day of the first month, and we ought to look for what is truly the fourteenth moon[131] for celebrating the course of our Lord’s Passion, still we can understand from this that to fix such a solemnity there is required either the perfection of the Church, or the fulness of clear faith, as the Prophet said when he spoke of the Son of God, that _his throne is as the sun before me, and as the perfect moon, it shall remain for ever_.
