Again, while liturgy has declined at roughly the same time that the Catechism was written, the Catechism is not replacing the liturgy. In fact, if the clergy better internalized the Catechism, we’d see less liturgical abuse.
How can anyone internalize anything if it keeps chaging? The Catechism from 80 years ago is not the same Catechism of today. In this fluid magisterial culture how can anyone know for sure what is orthodox and what is not?
Which "radition" do you adhere to?
