[I]t is imperative that the entire Catholic community in the United States come to realize the grave threats to the Church’s public moral witness presented by a radical secularism which finds increasing expression in the political and cultural spheres. The seriousness of these threats needs to be clearly appreciated at every level of ecclesial life. Of particular concern are certain attempts being made to limit that most cherished of American freedoms, the freedom of religion. Many of you have pointed out that concerted efforts have been made to deny the right of conscientious objection on the part of Catholic individuals and institutions with regard to cooperation in intrinsically evil practices. Others have spoken to me of a worrying tendency to reduce religious freedom to mere freedom of worship without guarantees of respect for freedom of conscience.
