On an Ordinariate Catechism...

While it is understood that the Catechism of the Catholic Church is the standard for the Ordinariates, the Catechism itself is designed as a source for producing particular catechisms. With that in mind I point you to two considerations of this.

From Vincent Uher's Tonus Peregrinus, writing about a text of Percy Dearmer:

I hope in due course the Ordinariates together with the Anglican Use parishes will produce a new particular Catechism with Services of Instruction like those with which we were once familiar. Of course, they would need to be adapted properly to our Catholic life. It would be an excellent way to bring quotes from the Anglican worthies to bear upon questions of the faith by way of footnote or direct quotation in the text...

In the September 2011 Holy Cross embertide issue of Anglican Embers, we published an article about devising an Ordinariate-specific Catechism. You can read author Hugo Mendez's thoughts at "An Ordinariate Catechism: Prospects and Possibilities" on the Anglican Embers page of the Anglican Use Society's web site.
