The lectures, organised by the Catholic Chaplaincy at the UEA, are one of the most popular public lecture series at the university.
The theme for this year's series is "Holiness', and the speakers are Professor Stephen Bullivant, of St Mary's University Twickenham (April 16); former Archbishop Rowan Williams (April 23); and Sr Ann Swailes of Cambridge University (April 30).
Lectures take place on Monday evenings at 6.30pm at UEA's Julian Study Centre and are free to attend.
Deacon Andrew Eburne, Catholic Chaplain at UEA, said: "I'm delighted to be able to announce such distinguished and diverse speakers. Stephen Bullivant has won numerous awards for his studies of Catholicism and the new atheism. Rowan Williams will be speaking on "Modern Urban Saints: Madeleine Delbrel, Dorothy Day, Maria Skobtsova'. Finally, Sr Ann Swailes, who is a very popular lecturer and chaplain from Cambridge University, will be speaking on the Dominican idea of holiness.
