 One group of pilgrims in early Celtic Christianity were the "Peregrinari Pro Christ", (Pilgrims for Christ), or "white martyrs", who left their homes to wander in the world.This sort of pilgrimage was an ascetic religious practice, as the pilgrim left the security of home and the clan for an unknown destination, trusting completely in Divine Providence.These travels often resulted in the founding of new abbeys and the spread of Christianity among the pagan population in Britain and in continental Europe.
