Apostasy is the formal religious disaffiliation or abandonment or renunciation of one's religion, especially if the motive is deemed unworthy. In a technical sense, as used sometimes by sociologists without the pejorative connotations of the word, the term refers to renunciation and criticism of, or opposition to, one's former religion. One who commits apostasy is an apostate, or one who apostatizes. The word derives from Greek αποστασία (apostasia), meaning a defection or revolt, from απο, apo, "away, apart", στασις, stasis, "stand", "standing". The term is sometimes also used to refer to renunciation of a belief or cause by (generally facetious) extension of the religious connotation, such as in reference to a political party or a sports team.On Sept.22,2009 Cardinal Angelo Bagnasco, President of the Conference of Catholic Bishops of Italy(Cei) issued a Cei directive which statedthat the revised Good Friday Prayer for the Conversion of the Jews is not for the conversion of present day Jews. Also, the Catholic Church had no intentions to actively convert Jews.
Apostasy is generally not a self-definition: very few former believers call themselves apostates and they generally consider this term to be a pejorative. Many religious movements consider it a vice (sin), a corruption of the virtue of piety in the sense that when piety fails, apostasy is the result. Unlike apostasy, heresy is the rejection or corruption of certain doctrines, not the complete abandonment of one's religion. Heretics claim to still be following a religion (or even to be the "true believers"), whereas apostates reject it entirely.(Wikipidia) Emphasis added
He mentioned that this was the assurance given earlier by Cardinal T.Bertone, Vatican Secretary of State.
