Megachurches are not just a US (or Nigerian, Korean...) phenomenon.
Even Secular France has got some, including Paris Christian Center in La Courneuve (North of Paris), attracting more than 4,000 regular attenders every week.
This is why the sudden and unexpected death of Selvaraj Rajiah, senior pastor of PCC, is a major event in the French protestant news.
This is one of the many questions the Pew Forum on Religion and Public Life helps to answer, due to a huge world survey on contemporary Christianity.
This comprehensive demographic study of more than 200 countries finds that there are 2.18 billion Christians of all ages around the world, representing nearly a third of the estimated 2010 global population of 6.9 billion. To know more, click here.
Even more than the Evangelical growth (between 600,000 and 750,000 Evangelicals in today's France), the Muslim growth is "the" big religious news of the last 40 years.
In 2011 France, there are an estimated five million Muslims living in the country. A century ago, they were referred to as "colonials". During the 1960s, they were known as "immigrants". Today, they are "citizens".
But how have the challenges facing each generation of immigrants changed?
While many speak openly about the collapse of organized Christianity in contemporary France, the heirs of French Reformers (including French-born John Calvin) are currently growing.
Although this is unexpected, it can't be denied. This process goes along with the spread of Evangelical new communities. A third of all current French protestants are Evangelicals, while 60% remain attached to the presbyterian and lutheran traditions. This new landscape draws questions and requires analysis.
