A personal relationship with God is strictly a tenet of evangelical Protestantism.
It is not a tenet of Catholicism, Eastern Orthodoxy, or to my knowledge mainline Protestants.
In Eastern Orthodoxy and Roman Catholicism it is ritual, institution, ceremony, and sacrament which mediate the relationship between God and the individual.
Which helps explain why there are so many denominations including the Republican Prosperity Christianity, a huge fad among the Alt-Right.
Is that like every American is Irish on March 17th and Mexican on May 5th?
