I would like to say openly that EWF and I are friends and though he doesn't understand my conversion and he didn't know until just today; he has been relying on post made before my conversion. A couple of things I wanted to respond to in your post to hopefully clear things up.
1) Unlike the reformers I haven't thrown out the baby with the bathwater. Namely, I did not have a personal growing relationship with God until I responded in faith to an evangelical sermon calling me to that relationship. With the knowledge I had at that time I began my faith journey and it was in evangelical circles. Therefore, there are certian things I am greatful for and as Francis Beckwith also testifies to I consider still a certain truths to be so in the faith I had while with evanglecals. Ie emphasis on scripture (though not sola scriptura) in my daily life and a continued prayer life to name just two aspects. Francis Beckwith would say he's and evangelical Catholic and I agree with him in some respect.
2)I do believe the Catholic Church is one Holy and Apostolic Church, as you say. However, I also believe there are Bishops, Priest, and layity that are carnal. And have been engaged in agressively attacking the Catholic Church by spouting things the Catholic Church never taught as doctrine. These people have used certain dispensations allowed for from Vatican II to make a whole sale assault on Catholic Beliefs. Ie... The Nancy Pelosi types. The Church teaches abortion is wrong but certain Bishops, Priest, layity give the wink wink nod nod that its ok and accept relativism in the Church allowing for this politician to support abortion against the teachings of the church. This group is also responsible for neglegence and inadhereance to scripture. In the Catholic point of view Apostolic Teaching is both Tradition and Scripture one not greater than the other each equally authoritative. But this group subjects one under the other. This is also the group that margenalize anything spiritual. I have started to teach Catholics I meet what their Catholic Faith Actually teaches. I've been involved in getting scriptural studies in my Parish, starting a mens group for prayer and scripture study, and help with RCIA. However, I see these things as being very Catholic and having been somewhat lost to a culture of liberalism attacking the Catholic Church. Its great to see the number of Catholics actually hungry for what their church teaches and what the scriptures have to say. I've encountered great priest who are involved with this and the Bishop I am under is very involved in this renewing Catachesis of Catholics bringing them back to the faith they claim to have. And if you look in the US you see a shift of this return to the original Catholic faith fighting back against the liberal fortifications within the clergy and layity and soon I think you'll find better educated catholics with in their faith and you'll see evangelical Catholics speaking up for the faith.
So there are Catholics today of great faith and some on the level of those you've heard spoken about like Mother Teresa, Francis of Assisi (who went to Egypt and witnessed the Gospel to the Caliphate), and others like them that are Truelly Catholic. And there are those that are secular Catholics or better described as Catholics in name only. It is this latter group I speak of as liberal and to which the Call has gone out to Come Home to the real Catholic faith.
