The evil of evangelical Christians are an affront to humanity.  In order to try and co-opt as much help to get trump out of office, I think that we should contact as many power-houses as possible. Ask that the Pope denounce trump as a heretic or worse (whatever the Pope can say and do).  That being said:

Pope Francis does not have a direct mailing address but you can contact the Vatican’s press office at

Alternately you can mail the pope via usual mail at this address:

His Holiness, Pope Francis PP.
00120 Via del Pellegrino
Citta del Vaticano
