Religion Dispatches

Religion Dispatches is a daily online magazine dedicated to the analysis and understanding of religious forces in the world today, highlighting a diversity of progressive voices and aimed at broadening and advancing the public conversation. Rigorous, open and respectful debate about central issues of the day is essential if democracies are to survive and flourish. Although religion is one of the most powerful forces shaping domestic and global politics today, it remains among the least understood and under-analyzed dimensions of our world. Partisan religious voices are all too common, but they do little to help us understand the dynamics of religion in the contemporary world. Whether dealing with fundamentalist movements at home and abroad, the purported clash of civilizations or public controversies over sexuality, immigration, and AIDS, gaining a deeper understanding of the role of religion, for good and for ill, is imperative. Religion Dispatches is an online magazine devoted to exploring the intersections of religion, values, and public life, nationally and globally. It aims to provide a platform for expert, critical exploration of religion in the contemporary world for a general readership. The goal of RD is to inform public debate by analyzing and critically engaging the role of religion and values on the most vital issues of our time. This will involve bringing a wider spectrum of perspectives into the conversation, especially voices that have been marginalized in most media, and increasing attention to progressive expressions of religion and values.

Societe des Bollandistes

Saints are inspirational, though some may belong more to the realm of folklore or even invention. For twenty centuries they have been influencing our world, our culture and our thinking in ways few people realise. The early martyrs whose exploits sustained generations of readers, the great mystical writers, pilgrimages and the trade in relics, accounts of prodigious healings and other miracles: the saints have inspired innumerable writers and artists, their very names identify towns and villages all over Europe and America, their patronage still inspires feasts and processions everywhere.

For almost four centuries the Bollandists have been at the forefront of hagiographic research [about Christian saints.]  Our team of experts, now both Jesuit and lay, is dedicated exclusively to the critical study of Greek, Latin, Oriental and modern hagiographic sources as well as to the history of the saints and their cults in all their aspects.  They have a library, a research centre, and do publications.  Look in our online catalog under author "Bollandists."  We do not offer Acta Sanctorum [lives of the Saints] online, but if you check this title in our online catalog you will find some vols are available in SPC or  via HathiTrust database.

While the project’s main commitment is to theology, it is responsibly informed by the latter two disciplines. Each section of the VCS is a virtual exhibition comprising a biblical passage, three art works, and their associated commentaries. The curators of each exhibition select artworks that they consider will open up the biblical texts for interpretation, and/or offer new perspectives on themes the texts address. The commentaries explain and interpret the relationships between the works of art and the scriptural text."
