Religion and politics may be off-limits as polite dinner party conversation, but if treated with complexity, they make for explosive theater. Artes de la Rosa, the visual and performing arts arm of the Rose Marine Theatre, presents one more performance of The Fifth Sun 7:30pm tomorrow night (Fri Sept 21). As directed by Artes artistic director Adam Adolfo, Nicholas A Patricca’s script is a dramatization of the life and death of Oscar Romero, the Roman Catholic archbishop of El Salvador who was killed by right-wing assassins in 1980. Romero was murdered for doing his job –– speaking out for his parishioners and against political tyranny –– but as with so many geopolitical dramas, the heroes and villains of the situation aren’t predictable. The Catholic Church bureauracy of the time, in particular, was not a staunch Romero ally.
