What is an essential element of Baha'i belief regarding humanity?

The oneness of humanity and the equality of all religions is a fundamental principle in Baha'i belief. This doctrine emphasizes that all people are interconnected and part of a single human family, promoting the idea that differences among races, cultures, and religions should be embraced rather than seen as divisive.

Baha'is advocate for the equality of all religions, asserting that every religious tradition contributes to the understanding of God and spiritual truth. This perspective upholds that no single religion holds an exclusive claim to ultimate truth and that all faiths possess inherent value. This belief system encourages unity among different groups and the recognition of shared human rights.

The other options present notions that contradict Baha'i teachings. For instance, the division of religions into higher and lower classes, as well as the supremacy of one race over others, contradicts Baha'i principles of equality and unity. Additionally, the belief that all humans are doomed to fail does not align with the Baha'i focus on hope, progress, and the capacity for individuals and societies to improve and evolve.
