All down history, as new plus much more deadly weapons had become used in war, these people were usually denounced by Christians. This happened a long time before the continuing development of modern warfare. Thus the crossbow, which gradually replaced the short bow from round the 10th century, was formally condemned from the second Lateran Council in 1139 AD.
In the guts ages the Turks began to use pyrotechnic compositions of their battles with Christians. This by using fire was condemned by Christendom as outrageous, barbaric and satanic. (This was hardly consistent, perhaps, simply because the Christian Byzantine Empire, centred in Constantinople, had protected itself from attack through the use of Greek Fire, probably burning oil projected with the enemy through a pump, since way back when.)
Gunpowder was invented through the Chinese around 1000 AD as well as the discovery was quickly followed, inside of a century, by ‘a vigorous progression of explosive weapons’ (Needham) but peaceful uses (in addition to for entertainment) were hardly whatsoever developed. There is not much evidence of its use within blasting. For two centuries weapons depending on gunpowder were utilized on a grand scale in China, producing devastation and fearful suffering on the list of Chinese as you move the power groups fought for supremacy.
Those that are disposed to criticise Christianity for that inconsistency of Christians should reflect that in China gunpowder was no sooner discovered personal computer was utilised in war without moral scruple, and never gunpowder only but effective poison ‘gas’ too (arsenical and mercurial minerals in pyrotechnic compositions). In the West, in contrast, the influence of Christianity long acted being a buffer, holding back continuing development of new scientific weapons since way back when. No other religion generally seems to have influenced mankind by doing this.
