Writing 
Shapiro's writings often challenge the bounds of the conventional Orthodox understanding of Judaism, using academic methodology while adhering to Modern Orthodox sensibilities. His publications have had mixed reception, ranging from criticism within the American publication Jewish Action, to support throughout the spectrum of Modern Orthodoxy  .

Shapiro's book, Between the Yeshiva World and Modern Orthodoxy: The Life and Works of Rabbi Jehiel Jacob Weinberg, a biography of Yechiel Yaakov Weinberg, was a National Jewish Book Award finalist. His second book, The Limits of Orthodox Theology: Maimonides' Thirteen Principles Reappraised, also a National Jewish Book Award finalist, argued against the popular Orthodox belief that Maimonides Thirteen Principles of Faith have always been regarded as unquestionable dogma. Gidon Rothstein, writing in the Association for Jewish Studies Review, called the book's collection of sources "remarkable."

Shapiro's 2006 book,  Saul Lieberman and the Orthodox, discusses how the Orthodox world related to Saul Lieberman, who was a recognized talmudic scholar who chose to teach at the Conservative Jewish Theological Seminary of America.

Shapiro's 2008 book, Studies in Maimonides and His Interpreters, looks at how Maimonides has been understood in both the traditional and the academic worlds. It also deals with Maimonides' attitude towards superstition.

In 2015, Shapiro's book Changing the Immutable: How Orthodox Judaism Rewrites Its History, was released, documenting the phenomenon of internal censorship in Orthodoxy; where Adam Ferziger said the book "is the outstanding product of a master of rabbinic literature and an extraordinarily sharp-eyed and meticulous scholar." Yair Hoffman, writing in the Hareidi online website Yeshiva World News, criticized the book, saying that "there is a plethora of material that simply should not have been included in the book because it does not back up his thesis." Ezra Glinter, writing in The Forward, praised Shapiro's "evenhanded, evidence-heavy approach" and that he was not a "polemicist," but said "his argument could also have benefited from a more critical thrust."

In 2019 Shapiro published Iggerot Malkhei Rabbanan which contains more than thirty years of correspondence with some of the world's most outstanding Torah scholars.
