The Most Reverend Alexander K Sample, Bishop of Marquette, has published a letter to be read at all Masses this coming weekend. It follows the lines of a model letter suggested by the USCCB (United States Conferene of Catholic Bishops) that all the bishops have been asked to send to their priests and comes in the wake of the Obama Administration's decision to force all employers, including Catholic employers, to offer health coverage that includes sterlization, abortion-inducing drugs, and contraception thereby denying Catholics and the Catholic Church the freedom to practise and live according to their religious beliefs.
Letter from Bishop Sample on Religious Liberty The US Conference of Catholic Bishops has a web page dedicated to the issue of the protection of conscience in the light of the US Department of Health and Human Services announcement. Visit it to see how you can contact Congress to protest this directive. (As a non-US citizen I don't believe I can do this myself.)
Cardinal Di Nardo also preached powerfully about this attack on religious liberty in his homily at the Basilica of the Immaculate Conception during the Mass in the evening before the Washington DC March for Life.
