Chaplaincy, Clergy, Prayer, Cancer and Measuring Religion and Health.

This third issue of JORH for 2023 revisits a number of themes previously highlighted in JORH, along with the addition of two new themes. Since JORH's first special issue on 'Chaplaincy' (JORH, 2022, 61:2), this area of research within JORH has now flourished, with a total of three JORH issues now incorporating the allied health discipline of chaplaincy. Two new article collections in this JORH issue relate to clergy 'faith leaders' and research related to 'prayer.' This issue also revisits the topic of cancer-a recurrent focus within JORH which has, over the past six decades, examined nearly every type of known cancer in the context of religion/spirituality. Finally, JORH collates once again, a number of articles relating to the empirical measurement of religion and health-an increasingly important area of research.
