text: Good point! That text (Mt 5:28) is quoted by Justin too, 1 Apol. 15.1. The words may be from Matthew (c. 80-90 CE) or his source rather than the historical Jesus, and they are meant to show that Jesus regrounds the Torah in the heart, rather than in external acts. Jesus seems to have been pretty understanding of sexual deviations in practice, as indicated by his welcoming attitude to various "sinful" women and to the centurion in Mt 8 (if the latter's relation to his pais is sexual, as several scholars claim to be likely). The same passage in Matthew says that "not a jot, not a tittle" of the Law will ever be relaxed (Mt 5:18), which Paul, claiming the spirit of Jesus, overrode. That statement, too, that may come from Matthew or his source rather than from the historical Jesus, and he may be reacting against Paul or some lax Paulinism. To square it with Paul we are obliged to say that the law is fulfilled to its last tittle when we fulfill the law of love.
