"Religious fundamentalism, even before it eliminates human beings by perpetrating horrendous killings, eliminates God himself, turning him into a mere ideological pretext."
-Pope Francis, Jan. 12, 2015, addressing the terrorist attacks in France
(numerous sources, see for example http://www.reuters.com/article/2015/01/12/us-france-shooting-pope-idUSKBN0KL0X120150112.)
On the narrow path to Truth in serving G‑d there is a major impediment
which is called “frumkeit” – a term which has no clear and
exact translation. Frumkeit is the natural urge and instinct to become
attached to the Creator. This instinct is also found amongst animals.
Dovid said, “The lion cubs roar for their prey and ask G‑d for their
food” (Tehilim 104:21). “He gives to the beast his food and to the young
ravens who call to Him” (Tehilim 247:9). There is no necessity why
these verses should be understood as metaphors.
-Rav Shlomo Wolbe zt"l, Alei Shur II p. 152ff., as translated (see also the elucidation there) at http://www.aishdas.org/asp/what-is-frumkeit.
