"Catholics and Islam"
John R. T. Lamont
"...Islam is the only major religion that was founded with the specific purpose of destroying and replacing Christianity, and that these denials of Christian teaching are intended to further this purpose; they are not simply expressions of theological disagreement. No other major religion contains specific denunciations of the basic Christian doctrines in its sacred texts...
...To some extent the question of terrorism is a side issue when it comes to the establishment of sharia law. The centrality of terrorism as a tool for Islamic extremists simply reflects the fact that they do not control a large and powerful empire, as was the case in previous centuries. Because of this fact, they have to resort to terror as a means of armed attack. Under the early Caliphs and the Ottoman Empire, the expansion of Islam was pursued by regular, well-organised military campaigns. These involved the use of terror at times - as is often the case in all military conflicts - but military victory by regular armies was historically the main tool of expansion of sharia law. This form of conflict was not less destructive and horrible than terrorist campaigns; in fact, it was far worse..."
