In the church at Antioch the Christians included Jews and gentiles and reached all the way from Herod’s foster brother to the slaves; and the naturally proud Greek Christian Gentiles of Macedonia showed a practical concern for the material needs of the Christian Jews in Jerusalem. The observable and practical love among true Christians that the world has a right to be able to observe in our day certainly should cut without reservation across such lines as language, nationalities, national frontiers, younger and older, colors of skin, levels of education and economics, accent, line of birth, the class system in any particular society, dress, short or long hair among whites and African and non-African hairdos among blacks, the wearing of shoes and the non-wearing of shoes, cultural differentiations and the more traditional and less traditional forms of worship.
