The Catholic Church also follows this biblical model in her

approach to paradosis/traditions.

Hence, there are paradosis/traditions which are unchangeable,

capital letter "T", "Traditions." These are the defined faith or

moral teachings based on the Bible but revealed by the Holy

Spirit as an authority in the Church (Acts 15:28). An example

from the history of the Catholic Church of Tradition (with a

capital letter "T") is the teaching on purgatory. This teaching of

the Church can never change.

There appear to be paradosis/traditions which are changeable,

small letter "t", "traditions." These are the "rules of the

organization, rules of the club." These change as people,

culture, faith and understanding develop. An example from

the history of the Catholic Church of tradition (with a lower

case letter "t") is the teaching on the prohibition of eating

meat on Fridays. This practice of mandatory abstinence

as penance in the Church has changed.
