Atheism for Lent is a contemplative practice that emerged out of ikon in Belfast, Ireland by Peter Rollins and other Pyrotheology co-conspirators.

This iteration of Atheism for Lent was created and curated by ikonNYC, specifically Jim Kast-Keat, Bo Eberle, Nelson Costa, and Andy Meisenheimer with contributions from Tad DeLay. They leaned on the work and writing of Peter Rollins, Katharine Moody, Merold Westphal, and William Lloyd Newell.
