You mean your particular sect of christianity. Christian Gnosticism and Catharism are just two historical christian sects who denied the reality of sense-perception, and who were purged for that. Not to mention christian mysticism, specially that of Meister Eckhart, or Spinozism, or any Neoplantonist interpretation of christian tradition. Christianity isn't a single theological or even metaphysical tradition, but a multitude of ones pinned to a more or less single oral tradition embodied in the bible. Specially, christianism doesn't entail physicalism. Furthermore, I don't see what's exceptional about "the world" being "real". Even the Eleatics and the Neoplatonists would've agreed to that, granted that "the world" be their "One", even though they asserted that sense-perception is illusory. If these words are taken in their most general sense, then this proposition becomes a platitude. You might as well say that "whatever is, is". And no one has ever seriously argued that nothing exists (Gorgias of Leontini did only in jest).
