===Transfinalization===
{{related|[[Teleology]]|[[Extrinsic finality]]|[[Intrinsic finality]]}}
Rahner was a critic of [[substance theory]] and was concerned about the [[Final cause|finality]] of liturgy. He proposed instead to rename [[transubstantiation]] into ''transfinalization''.{{citation needed|date=December 2022}} John Hardon defined "transfinalization" as: 

{{blockquote|The view of Christ's presence in the Eucharist that the purpose or finality of the bread and wine is changed by the words of consecration. They are said to serve a new function, as sacred elements that arouse the faith of the people in the mystery of Christ's redemptive love.<ref name='haldon'>

[[Pope Paul VI]] in the encyclical ''[[Mysterium fidei (encyclical)|Mysterium fidei]]'', mentioning the term 'transfinalization' one time, without citing Rahner's name, stated:
{{blockquote|[...]it is not permissible to[...] discuss the mystery of transubstantiation without mentioning what the [[Council of Trent]] had to say about the marvelous conversion of the whole substance [...] as if they involve nothing more than "[[transignification]]," or "transfinalization" as they call it...{{sfn|Paul VI|1965}} }}

Haldon states that in ''Mysterium fidei'' Pope Paul VI "condemned" the notion of "transfinalization", which was one of the "principal errors about the [[Real presence of Christ in the Eucharist|Real Presence]] that were already current in his day".<ref name="haldon" />
