What you are calling “Christian” is very congruent with Islam.
Each is creating their own deity and gospel, disregarding Yeshua’s almost completely.
Yehova provided his feasts for eternity, and replacing them with man’s idea of what they should be will not please him.
His feasts provide knowledge of the future, needed for navigating through Satan’s maze. Man’s feasts blind one to the path Yehova has provided. That is the same for Islam, Catholicism, Shintoism, Hinduism, Buddhism, and every other ism.
Seek out the narrow gate!
Repugnant. Grotesque. But that's your 'christ', and welcome to it.
