Religious expressions refer to the various outward manifestations of inward religious faith in social interactions. Inevitably, studies on religious expressions have long been conducted across academic fields but inadequately reviewed. To examine how the publication and citation patterns have developed over time, this bibliometric study retrieved bibliographic data from Scopus on August 22, 2022 by providing a search query of related terms in titles, abstracts, and keywords. Refined with OpenRefine version 3.5.0, the data of 1,341 documents were submitted to Bibliometrix R-package version 4.0.
