In their thirties. The mistake is calling it re-aquiring a faith. They would be re-aquiring a religion, which is a belief system and does not have anything to do with faith. It is a giving up of personal responsibility to search for the truth on their own. They give that up to the priesthood.
Disclaimer: that is only my opinion.
That would be find and dandy if the Catholic Church had been expounding on them constantly, but that isn't the case.
Like I said, growing up under the Catholic Church no crucifix was worn, nor was it expected. After the falling away from the Church and then the reunificaion with the Church, the person decided to wear a crucifix at all times. The Church still did not require it to be worn.
As for your opinion about "faith and religeon"..... that's right, it is your opinion and only your opinion and in this case that opinion would be wrong.
