Latin: strangers, transients
In the law of the Church, those who are sojourning outside the place of their domicile or quasi-domicile which they retain. They differ from vagi in that the latter have neither domicile nor quasi-domicile. A peregrinus is bound to observe the general laws of the Church that are in force in the place where he actually is, irrespective of whether they are in force in the place of his residence or not. But he is not bound to observe the particular laws of his domicile or quasi-domicile, unless his non-observance of them would offend in his place of residence or if they were personal. Neither is he bound to observe the particular laws of the territory where he is staying for the time being, unless they provide for public order or regulate the solemnities of acts.
