2 How am I distressed, think you, when I call to mind that on the festival days the multitudes assembled resemble the broad expanse of the sea, but now not even the smallest part of that multitude is gathered together here? Where are they now who oppress us with their presence on the feast days? I look for them, and am grieved on their account when I mark what a multitude are perishing of those who are in the way of salvation, how large a loss of brethren I sustain, how few are reached by the things which concern salvation, and how the greater part of the body of the Church is like a dead and motionless carcass.
“And what concern is that to us?” you say. The greatest possible concern if you pay no attention to your brethren, if you do not exhort and advise, if you put no constraint on them, and do not forcibly drag them hither, and lead them away out of their deep indolence. For that one ought not to be useful to himself alone, but also to many others, Christ declared plainly, when He called us salt, and leaven, and light: for these things are useful and profitable to others. For a lamp does not shine for itself, but for those who are sitting in darkness: and you are a lamp not that you may enjoy the light by yourself, but that you may bring back yonder man who has gone astray.
For what profit is a lamp if it does not give light to him who sits in darkness? And what profit is a Christian when he benefits no one, neither leads any one back to virtue? Again salt is not an astringent to itself but braces up those parts of the body which have decayed, and prevents them from falling to pieces and perishing. Even so do thou, since God has appointed you to be spiritual salt, bind and brace up the decayed members, that is the indolent and sordid brethren, and having rescued them from their indolence as from some form of corruption, unite them to the rest of the body of the Church.
And this is the reason why He called you leaven: for leaven also does not leaven itself, but, little though it is, it affects the whole lump however big it may be. So also do ye: although you are few in number, yet be ye many and powerful in faith, and in zeal towards God. As then the leaven is not weak on account of its littleness, but prevails owing to its inherent heat, and the force of its natural quality, so ye also will be able to bring back a far larger number than yourselves, if you will, to the same degree of zeal as your own.
Now if they make the summer season their excuse: for I hear of their saying things of this kind, “the present stifling heat is excessive, the scorching sun is intolerable, we cannot bear being trampled and crushed in the crowd, and to be steaming all over with perspiration and oppressed by the heat and confined space:” I am ashamed of them, believe me: for such excuses are womanish: indeed even in their case who have softer bodies, and a weaker nature, such pretexts do not suffice for justification.
Nevertheless, even if it seems a disgrace to make a reply to a defence of this kind, yet is it necessary. For if they put forward such excuses as these and do not blush, much more does it behoove us not to be ashamed of replying to these things. What then am I to say to those who advance these pretexts? I would remind them of the three children in the furnace and the flame, who when they saw the fire encircling them on all sides, enveloping their mouth and their eyes and even their breath, did not cease singing that sacred and mystical hymn to God, in company with the universe, but standing in the midst of the pyre sent up their song of praise to the common Lord of all with greater cheerfulness than they who abide in some flowery field: and together with these three children I should think it proper to remind them also of the lions which were in Babylon, and of Daniel and the den: and not of this one only but also of another den, and the prophet Jeremiah, and the mire in which he was smothered up to the neck. And emerging from these dens, I would conduct these persons who put forward heat as an excuse into the prison and exhibit Paul to them there, and Silas bound fast in the stocks, covered with bruises and wounds lacerated all over their body with a mass of stripes, yet singing praises to God at midnight and celebrating their holy vigil. For is it not a monstrous thing that those holy men, both in the furnace and the fire, and the den, and among wild beasts, and mire, and in a prison and the stocks, and amidst stripes and jailers, and intolerable sufferings, never complained of any of these things, but were continually uttering prayers and sacred songs with much energy and fervent zeal, while we who have not undergone any of their innumerable sufferings small or great, neglect our own salvation on account of a scorching sun and a little short lived heat and toil, and forsaking the assembly wander away, depraving ourselves by going to meetings which are thoroughly unwholesome? When the dew of the divine oracles is so abundant do you make heat your excuse? “The water which I will give him,” says Christ “shall be in him a well of water springing up into everlasting life;” and again; “He that believes in me as the Scripture has said, out of his belly shall flow rivers of living water.” Tell me; when you have spiritual wells and rivers, are you afraid of material heat? Now in the market place where there is so much turmoil and crowding, and scorching wind, how is it that you do not make suffocation and heat an excuse for absenting yourself? For it is impossible for you to say that there you can enjoy a cooler temperature, and that all the heat is concentrated here with us:— the truth is exactly the reverse; here indeed owing to the pavement floor, and to the construction of the building in other respects (for it is carried up to a vast height), the air is lighter and cooler: whereas there the sun is strong in every direction, and there is much crowding, and vapour and dust, and other things which add to discomfort far more than these. Whence it is plain that these senseless excuses are the offspring of indolence and of a supine disposition, destitute of the fire of the Holy Spirit.
