He was born in Fullerton, California and educated at Pomona College (where he graduated with a BA in 1921) and Boston University (where he gained his PhD in 1926). Marshall was the professor of philosophy at Albion College from 1926 until 1946 and professor of philosophy at the University of the South in Sewanee, Tennessee from 1946 until 1968. He was also editor of the Anglican Theological Review during 1959–1965.^[3]

In 1949 Marshall's book on the theology of William Porcher DuBose, The Word Was Made Flesh, was published by the University of the South Press with an introduction by the late Episcopal bishop of New York City, William T. Manning.^[4] Norman Pittenger appraised the work as a "convenient, logically developed outline of the whole philosophical-theological view of Du Bose".^[4]

Marshall's 1956 work, Hooker's Theology of Common Prayer, is a guide to Richard Hooker's fifth book of his Of the Lawes of Ecclesiastical Politie.^[5] In his review, Massey H. Shepherd said it was "nothing less than an up-to-date apology for the Book of Common Prayer" and "an outstanding example of how old classics can be made to speak in contemporary accents to living issues of theology".^[5]

In 1963, Marshall composed a fuller treatment of Hooker's theology in Hooker and the Anglican Tradition: An Historical and Theological Study on Hooker's Ecclesiastical Polity. Marshall argued that Hooker in his Of the Lawes of Ecclesiastical Politie only aimed to refute the Puritans in Books II–V, i–xlix and VI, and that Books I, V, l–lxxxi, VII–VIII were intended as a Summa Theologiae modelled on Thomas Aquinas and in which Hooker imitated Aristotle's method of continual discourse.^[6]

Marshall married Elizabeth Southard on May 26, 1923, and they had one son.^[3]
