“Webster defines racism as the practice of racial discrimination or persecution. The Jews were God’s chosen people, so were they not racist? They called the Samaritans dogs because they were a mixed race, had nothing to do with the Gentiles, and weren’t permitted to marry Gentiles to keep the Jewish nation pure. Maybe I’m wrong; if so help me to understand.”
The prohibition against marrying Gentiles was to keep the Jewish nation which would produce the Messiah pure in a religious sense (Ex. 34:13-16; Deut. 7:3-4; Josh. 23:12-13; cf. 1 Kings 11:1-8; Ez. 9-10; Neh. 13:23ff). However, marriage to Gentiles was allowed in some cases (cf. Deut. 21:10-14). Thus, the prohibition was not founded out of racist discrimination, but rather out of a desire to keep the Israelites loyal to God alone.
God has never shown partiality between Jew and Gentile (Rom. 2:9-11). True, he set Abraham’s descendants apart to produce the Messiah because of Abraham’s faith (Gal. 3:6; Rom. 4:9-12). Yet, remember that Abraham was an uncircumcised Gentile at the time God set him apart (Rom. 4:9-12).
God also communicated with and/or blessed in various ways individual Gentiles such as Abel, Noah, Job, Melchizedek, Jethro, Balaam, Rahab, Ruth, etc. He also indirectly and directly reached out to and/or blessed many Gentile nations and their kings, such using Joseph with Pharaoh’s Egypt, Daniel with Nebuchadnezzar’s Babylon, Daniel and Esther with Darius’ and Xerxes’ Persia, Jonah and Nahum with Assyria, Obadiah with Edom, Zephaniah with Ethiopia, and Amos and Ezekiel with Ammon, Phoenicia, Egypt, and Edom.
God also offered his Son for the whole world and the gospel to both Jew and Gentile (John 3:16; Rom. 1:16; Tit. 2:11).
Thus, any racist discrimination and prejudice against Gentiles by Jews did not originate with God. Rather, it came about through the inordinate, selfish pride of the Jews who took their divine national sanctification to mean more than it did (Matt. 3:8-9; John 8:37-41). Jesus reached out to and showed kindness to Samaritans and Gentiles, as did his faithful followers (John 4; Mark 7:24-30; Acts 8:5ff; 10-11; 15; etc.) Prideful, racist Jews tried to either prevent or limit compassionate outreach to Gentiles (cf. Gal. 1-5; Col. 2: Rom. 2-11).
