In most denominations, I believe, preaching is on scripture. In my church most every Sunday it is the Gospel reading. The sermon is supposed to be a bridge explaining how scripture written more or less 2000 years ago can be applied to life today. The Gospels which are the biographies of Jesus don’t easily go into social issues - but in living a righteous life. It speaks to me.
So the woman taken in adultery was not a social issue and the woman at the well also? That was all Yeshua spoke about was how sin broke the person and also the nation. Everything in Torah and spoken by the Master was about today and everyday for two thousand years. If you want to shrink the church step away from there 501c tax break. You can not serve two masters as you will love one and hate the other. Give onto Rome that which is Rome’s and onto G_D that which is G_Ds. Sounds social to me.
