Is syncretism a religion of common value?

The statement is true. Syncretism is a religion of common values.

Explanation:

In religion, syncretism is called that religious belief or faith that combines the characteristics, beliefs, deities or customs of two or more different religions, homogenizing them and creating from them a new religion.

Generally, these beliefs follow two characteristic patterns: either they adapt majority religions to contexts of minority beliefs, such as Creole or Africanist beliefs, where components of Christianity are mixed with local religions; or through the mixture of two different majority religions among themselves, as is the case of Sikhism, which combined Hinduism and Islam to create a unified religion in India.

As can be seen, in both cases there is an amalgamation of beliefs that are modified and adapted to the particular situation of a given human group.
