Can a Jew and a Christian be "Brothers"???

Obviously Jeremy Gimpel believes that they are the Jews brothers. If you are not aware of who this person is and the affiliation he has with the idolaters of geezus their man/god/savior - do visit palmtreeofdeborah.blogspot.com and read the series "war with the Waller Family" and others like them. Do notice the t-shirt that this idolater is wearing.
