"It is difficult to realize that three years have elapsed since Your Holiness announced that you planned to convene an Ecumenical Council of the Catholic Church--the first in almost a hundred years. During these three fateful years, millions of my fellow citizens in the United States, including many who do not belong to the Catholic Church, have followed with lively and sympathetic interest the work of the various preparatory Commissions appointed by Your Holiness to draw up the agenda for this extraordinarily important Council. They have also read, with particular interest and with genuine admiration for your all-embracing concern for the welfare of humanity, the several inspiring statements issued by Your Holiness on the background and purposes of the Council."
