From a wonderful blog post by Msgr. Charles Pope of the Archdiocese of Washington titled The Church Must Be Willing to Be A Sign of Contradiction:

“That world hates us is not necessarily due to the fact that we have done anything wrong. It is often a sign that we have done something precisely right for it is often our lot, as the Body of Christ, to be a ?sign of contradiction.? That is to say that we must announce the Gospel to a world that is often and in increasing measure, stridently opposed to it. St. Paul admonished Timothy to preach the Gospel, whether in season or out of season (2 Tim 4:2). Increasingly now it is out of season and the world hates us for what we say. But we can do no other, for if we are faithful, we must speak.”
