1995

For Catholics it is easy to recognize 1995 as a key moment, being the year of the issue of John Paul II's encyclical letter on ecumenism, Ut Unum Sint. This may be the only papal encyclical that begins with a personal declaration: "I carry out this duty with the profound conviction that I am obeying the Lord, and with a clear sense of my own human frailty."
