Senator Eugene J. McCarthy (D-Minn.) arrives in Cambridge today to deliver three lectures on "Religion and Politics."

He will give the William Belden Noble Lectures at 8 p.m. tonight, Tuesday, and Wednesday in Memorial Church.

Prominent religious thinkers, like Paul Tillich and Robert Mcaffee Brown, are usually invited to give the lectures. McCarthy, a Roman Catholic, is one of the few laymen ever invited.

Charles P. Price '41, Preacher to the University, said last night McCarthy is the first politician to speak since Theodore Roosevelt '80 appeared in 1910.

Tonight McCarthy will discuss religious belief and political action. On Tuesday he will treat the problems of morality in government, and on Wednesday examine the moral aspects of foreign policy.
