Christian religious antisemitism is often expressed as anti-Judaism, i.e., it is argued that the antipathy is to the practices of Judaism. As such, it is argued, antisemitism would cease if Jews stopped practicing or changed their public faith, especially by conversion to Christianity, the official or right religion. However, there have been times when converts were also discriminated against, as in the case of liturgical exclusion of Jewish converts in the case of Christianized Marranos or Iberian Jews in the late 15th century and 16th century accused of secretly practising Judaism or Jewish customs.[3]
