Snippets from The Spreading Flame by F.F. Bruce.
(Which is a history of the rise and progress of
Christianity from its beginnings through to the
conversion of the English.)

P. 294
Nor can any Christian or group of Christians contract
out of some share of responsibility for these scandals;
un-Christian behaviour on the part of any Christian
is a disgrace to all Christians. (Ouch)

P. 296
Doctrinal controversies which should have been confined
to the calm consideration of synod and lecture-room
were bandied about in the market-place and became the
playthings of popular turbulence. (Perhaps the market-
place has been replaced by blogville.)

P. 304
For Arianism reflected a temporary phase of thought,
and by conceiving of Christ as neither God nor man,
but something in between, it deprived Him of any real
mediatorship or saving power. (It always comes back
to who Christ is and what His relationship to the
Father is.)

P. 309
Athanasius stood for principle at any price; Constantine
for concord at any price. (Time to examine myself, I fear
I am weak.)

P. 311
On the one side and on the other attempts were made to
accommodate the Christian faith to current modes of
thought, but these accommodations usually proved, on
scrutiny, to be basically inconsistent with the substance
of the faith itself. And this was just as well, for the
current modes of thought to which people tried to accommodate
the faith sooner or later went the way of most modes of
thought;...(This sounds like a commentary on post-modernism
and the attempt to align Christianity with it.)

P. 314
The various heresies that sprang up in the earliest Christian
centuries are by no means out of date. They reappear
regularly in one form or another from generation to generation;
as Miss Dorothy Sayers has emphasized, they are "largely the
expression of opinion of the untutored average man, trying
to grapple with the problems of the universe at the point
where they begin to interfere with his daily life and thought."
(Not only do I agree with this, but, I had to include the
quote from one of the greatest mystery writes of all time.)
