Abstract
This article formulates a series of hypotheses concerning the religious strategies and practices in the world of Western European migration. Church activities are taken into con sideration, as well as the practices of the migrants themselves, but they are only seen in the context of Christianity.
For the authors, the cognitive, symbolic and practical system which forms the religious behaviour of migrants has to be seen in relation to the milieu which they are living in, the social class which they belong to, and the role which they are assigned to play in both the country of departure and the country of arrival. We may also take into consideration the nature of " migratory projects " which influence the religious practices of the migrants.
On this background one can understand and analyse the different observable religious migratory fields.
