Rebecca Groothuis and other scholars calling Galatians 3:28 the most important egalitarian text

Rebecca Groothuis (spelled G-R-O-O-T-H-I-U-S, pronounced 'Grotheis') calls Galatians 3:28 'probably the single most important equality text' for egalitarians. In Discovering Biblical Equality (p.134), Ronald and Beverly Allen call it 'the feminist credo of equality' in their book Liberation Traditionalism: Men and Women in Balance.
