The fundamental belief of Interfaith Spirituality is that there is one Universal Divine Essence and each culture and tradition has their unique way of integrating that Divine Essence into their daily lives.

The term interfaith or interfaith dialogue refers to cooperative and positive interaction between people of different religious traditions, (ie. "faiths") at both the individual and institutional level with the aim of deriving a common ground in belief through a concentration on similarities between faiths.

It is distinct from syncretism or alternative religion, in that dialogue often involves promoting understanding between different religions to increase "tolerance" towards others, rather than to synthesize new beliefs. The history of religion shows that conflict has been more the state of affairs than dialogue.
