Pantheism "Interfaith dialogue refers to cooperative, constructive, and positive interaction between people of different religious traditions (i.e. "faiths") and/or spiritual or humanistic beliefs, at both the individual and institutional levels. It is distinct from syncretism or alternative religion, in that dialogue often involves promoting understanding between different religions or beliefs to increase acceptance of others, rather than to synthesize new beliefs."

One way to understand pantheism in the context of Christianity would be to think what would happen if you mixed Buddhism with Christianity. What would happen if we meditated to Jesus instead of praying to Jesus? If we wanted to understand panentheistic Christianity then perhaps we could view the religion in light of its Jewish ancestry. Christianity and Islam differ quite a lot when it comes to the afterlife. Yet it's possible to compare the two culturally when it comes to earthly life. So how would we feel if Christianity were like a social bond between the individual and the community? It might be easier to understand the trinity in Christianity if we were to contrast it with the different versions of Hindu's God.
"Multiple religious belonging, also known as double belonging, refers to the idea that individuals can belong to more than one religious tradition. While this is often seen as a common reality in regions such as Asia with its many religions, religious scholars have begun to discuss multiple religion belonging with respect to religious traditions such as Judaism, Christianity, and Islam."
"According to Baháʼí teachings, religion is revealed in an orderly and progressive way by a single God through Manifestations of God, who are the founders of major world religions throughout history; Buddha, Jesus, and Muhammad are noted as the most recent of these before the Báb and Baháʼu'lláh. Baháʼís regard the world's major religions as fundamentally unified in purpose, though varied in social practices and interpretations. The Baháʼí Faith stresses the unity of all people, explicitly rejecting racism, sexism, and nationalism. At the heart of Baháʼí teachings is the goal of a unified world order that ensures the prosperity of all nations, races, creeds, and classes."
