Below is a note from Dr. Holly Taylor Coolman of Providence College on a new opportunity for Thomists to participate in the annual meeting of the Catholic Theological Society of America (CTSA):
I thought you might be interested to know about an interesting development.
About six weeks ago, my friend and colleague Michon Matthiesen and I received word that a proposal we made to the Catholic Theological Society of America had been accepted. Beginning with the meeting in June of 2013, the CTSA will have a session devoted exclusively to Aquinas. (Our proposal was accompanied by the signatures of almost 40 CTSA members, signalling widespread support for the new initiative.)
A Call for Papers related to this session will go out shortly after the Society’s Annual Meeting in June of the coming year.
We plan to post updates here: http://sites.google.com/site/aquinasctsa/
Thanks for all you do at thomistica.net!
