Ok, let's play...
Here (St.) Augustine (in AD 413-426 or so) does just what modern Christians loathe when it's done to them: namely, when people trot out the tired old "If God exists, why does He allow suffering and catastrophes" argument.
Augustine, blames the fall of Rome for the iniquities of its inhabitants, says Christianity had nothing to do with it's decline. He omits any details of the various other religions so as to denounce them.
Mithraism, one of the preferred religions of the actual Roman soldiers, in fact, had its own internal hierarchy, morality, baptism and theology. And Isis worship, the other Legion religion had it's own ascetic practices. (This paragraph a paraphrase from "The Civilization of Rome" - Pierre Grimal)
Yet no mention of the details by Augustine, to better demonize the non-Christians, of course.
Augustine, City of God II
Chapter 22. That the Roman Gods Never Took Any
Steps to Prevent the Republic from Being Ruined by
But what is relevant to the present question is
this, that however admirable our adversaries say
the republic was or is, it is certain that by the
testimony of their own most learned writers it had
become, long before the coming of Christ, utterly
wicked and dissolute, and indeed had no existence,
but had been destroyed by profligacy. To prevent
this, surely these guardian gods ought to have
given precepts of morals and a rule of life to the
people by whom they were worshipped in so many
temples, with so great a variety of priests and
sacrifices, with such numberless and diverse
rites, so many festal solemnities, so many
celebrations of magnificent games. But in all
this the demons only looked after their own
interest, and cared not at all how their
worshippers lived, or rather were at pains to
induce them to lead an abandoned life, so long as
they paid these tributes to their honor, and
regarded them with fear. If any one denies this,
let him produce, let him point to, let him read
the laws which the gods had given against
sedition, and which the Gracchi transgressed when
they threw everything into confusion; or those
Marius, and Cinna, and Carbo broke when they
involved their country in civil wars, most
iniquitous and unjustifiable in their causes,
cruelly conducted, and yet more cruelly
terminated; or those which Sylla scorned, whose
life, character, and deeds, as described by
Sallust and other historians, are the abhorrence
of all mankind. Who will deny that at that time
the republic had become extinct?
Possibly they will be bold enough to suggest in
defence of the gods, that they abandoned the city
on account of the profligacy of the citizens,
according to the lines of Virgil:
"Gone from each fane, each sacred shrine, Are
those who made this realm divine."
But, firstly, if it be so, then they cannot
complain against the Christian religion, as if it
were that which gave offence to the gods and
caused them to abandon Rome, since the Roman
immorality had long ago driven from the altars of
the city a cloud of little gods, like as many
flies. And yet where was this host of divinities,
when, long before the corruption of the primitive
morality, Rome was taken and burnt by the Gauls?
Perhaps they were present, but asleep? For at
that time the whole city fell into the hands of
the enemy, with the single exception of the
Capitoline hill; and this too would have been
taken, had notthe watchful geese aroused the
sleeping gods! And this gave occasion to the
festival of the goose, in which Rome sank nearly
to the superstition of the Egyptians, who worship
beasts and birds. But of these adventitious evils
which are inflicted by hostile armies or by some
disaster, and which attach rather to the body than
the soul, I am not meanwhile disputing. At
present I speak of the decay of morality, which at
first almost imperceptibly lost its brilliant hue,
but afterwards was wholly obliterated, was swept
away as by a torrent, and involved the republic in
such disastrous ruin, that though the houses and
walls remained standing the leading writers do not
scruple to say that the republic was destroyed.
Now, the departure of the gods "from each fane,
each sacred shrine," and their abandonment of the
city to destruction, was an act of justice, if
their laws inculcating justice and a moral life
had been held in contempt by that city. But what
kind of gods were these, pray, who declined to
live with a people who worshipped them, and whose
corrupt life they had done nothing to
Such religious bigotry. Essentially "Your god/s are worthless if they don't prevent your suffering". Is it then fair to ask where was Jesus on 9/11? of course not. The argument is dishonest. It reduces religion to mere talisman, the very thing the "better" religions are supposed to be "above".
How at odds with the beautiful (downright American) Edict of Milan of AD 313:
When I, Constantine Augustus, as well as I Licinius Augustus fortunately met near Mediolanurn (Milan), and were considering everything that pertained to the public welfare and security, we thought -, among other things which we saw would be for the good of many, those regulations pertaining to the reverence of the Divinity ought certainly to be made first, so that we might grant to the Christians and others full authority to observe that religion which each preferred; whence any Divinity whatsoever in the seat of the heavens may be propitious and kindly disposed to us and all who are placed under our rule And thus by this wholesome counsel and most upright provision we thought to arrange that no one whatsoever should be denied the opportunity to give his heart to the observance of the Christian religion, of that religion which he should think best for himself, so that the Supreme Deity, to whose worship we freely yield our hearts, may show in all things His usual favor and benevolence. Therefore, your Worship should know that it has pleased us to remove all conditions whatsoever, which were in the rescripts formerly given to you officially, concerning the Christians and now any one of these who wishes to observe Christian religion may do so freely and openly, without molestation. We thought it fit to commend these things most fully to your care that you may know that we have given to those Christians free and unrestricted opportunity of religious worship. When you see that this has been granted to them by us, your Worship will know that we have also conceded to other religions the right of open and free observance of their worship for the sake of the peace of our times, that each one may have the free opportunity to worship as he pleases; this regulation is made we that we may not seem to detract from any dignity or any religion.
So after Christians get their proverbial inch, 100 years later or so, they started taking their mile...
