On similarities between the way first century Christians treated Gentiles and the way twenty first century Christians treat Gays and Lesbians:
“The apostle Peter was just such a person - strong in his faith, yet firmly entrenched in his belief that the Messiah had come to offer salvation only to the Jews. This belief appeared to be supported by Scripture as it was interpreted at that time. The Gentiles (non-Jews) were considered so unclean that Jews were forbidden to enter their homes or to eat meals with them.” - p. 148. Gay Christian books.
“Peter and the group of Jews he brought with him were astonished, for they had never seen nor heard that salvation could come to anyone but the Jews.” p. 150.
