I'm guessing you're not familiar with independent protestant churches, much less Pentecostal and Evangelical ones.
On the contrary, I'm all too familiar with them, and historically in the period you are covering they didn't have the impact of the mainline Protestant gatherings and assemblies.
These churches are "Non-Ceremonial & Non-Liturgical" often completely extemporaneous and VERY popular in the USA.
''very popular'' I guess to the people in them, others may not have that same feeling I imagine...
(like I said, they go back to pre American Revolutionary times. I guess your local church missed out on the 1st and 2nd "Great Awakenings"
As a man who was born Papist, committed to an ardent traditional Papism as a young adult, and who now is an Orthodox Christian of Old Ritualist sympathies, you might say that. I am however aware that the phenomena you mention I believe was more of a Methodist affair initially, and they still had a liturgy, sacraments, bishops, etc.. At that time.
The first Prayer was composed by a senior army chaplain and distributed for use in services and to individual Army personnel. (it worked to.)
Again, as a localized and temporary American phenomena.
Twain's "Prayer" evidences his response to the very popular custom of church invocations of death and destruction upon their enemies at that time.
Again, an Infidel, attacking an easy target, the ''low hanging fruit'' so to speak. It happens pretty often.
I'm sorry if the facts disturb your idyllic view of Christian morality,
If you genuinely knew of ''christian morality'' you might realize that Christians are sinners by admission, and we are well aware of our struggles to fulfill the Lord's commandments in this life, even as we do so with His help. So I am neither disturbed nor do I have an idyllic view. Hospitals are for sick people, and the condition is terminal but yet not permanent.
but Christians are as blood thirsty and hysterical as the worst of the Islamic Jihadi preachers.
If they are, they are going against the teachings of their faith, contra the Muslims. Plus, one would need to define ''blood thirsty'' and ''hysterical'', as Christians are not enjoined to be pacifists in every circumstance. Seems you've let your imagination and emotion get the better of you, if I didn't know any better.
Another typical example of a non-Christian lecturing Christians on what their religion is and is not
But man is a fickle and disreputable creature and perhaps, like a chess-player, is interested in the process of attaining his goal rather than the goal itself.
