"Compromise with those not of the Faith is at all times the deadliest of errors. Here precisely is the danger of religious indifferentism. Here is the danger of socialism. Here is the danger of mixed marriages. Here is the danger of seeking to keep at all costs the golden opinion of the world and fearing its contempt. Here is the danger of education in non-Catholic schools, no matter how innocent they may seem to be."--Fr. Joseph Husslein, The Catholic's Work in the World (Imprimatur 1917), pp. 93-94
