“Red letter” Christians only follow selective, out-of-context quotes by Jesus which conform to their own sensibilities …

While discounting the rest of Scripture.

Theirs is a pick-and-choose Jesus, supported by a fractured logos as they seek to divide the Living Word from His written Word of Scripture.

As a result, they know not Christ …

Which may explain their habitual existential angst and inability to create either viable disciples or functional churches.
