Here in southern Belize, where I'm slowly working on dissertation research, it's hard to miss the influence of the Church on the local populations. There are a variety of churches trying to position themselves as the faith of choice here in Punta Gorda and in the villages of Toledo. Roman Catholics seem to be the most rooted here in the region, as evidenced by the many RC schools scattered throughout the district. However, Protestants continue to make inroads, and are quickly becoming a force in religious lives of many.
Other religious groups are active as well. It is not uncommon to see a Maya woman in traditional dress - except for her Mennonite bonnet. The Jehovah's Witness has a number of buildings here too, and one can often witness the men in suits walking with bibles in hand, hoping to find another convert. And white missionaries from various faiths seem to be here in various guises. The above picture is of a church in the village of Boom Creek, and in it's construction, Maya tradition (the thatch roof) can be seen blended with icons of the Church (large crosses cut into the front walls).
A friend doing research in one of the nearby Maya communities has described the religious division in the village: Catholics mostly inhabit one side of the creek, and Protestants the other. She occasionally has drinks with the Catholics, while such activity is forbidden on the other side of the creek. The divisions based on religious lines appear deeply rooted, and have consequences in the daily life of the village.
And what becomes of traditional Maya spirituality in such circumstances? For me, it is hard to say definitively, as my research (or that of my friend's) is not on religious and spiritual issues. However, having worked with Maya healers, it is safe to say the Maya spirituality remains alive for many here. It appears that there is little conflict between traditional spirituality and missionary religion in the minds of those who practice.
