Pope Innocent III, Fourth Lateran Council, 1215: “Moreover, we determine to subject to excommunication believers who receive, defend, or support heretics.”
Does this mean it’s sinful to support a pentecostal missionary for example?
What do they mean “receive” heretics? If I let a Protestant (as in one who’s Anti-Catholic) into my house, would this be a sin then?
If I let an adherent of a Protestant denomination into my house (a ‘material’ heretic), would I be sinning then?
