That’s a graciously intended gesture, to be sure. Whether it is positioned to be generally accepted theology in the Catholic church is another question. That was not an ex cathedra remark was it?
Don’t know about theology, but an individual who has been baptised in the name of the Trinity is considered Christian by Catholics—they are part of the Church, if not the fullness of it, and Christians because of this, at least to my understanding. So if a Baptist wants to be a Catholic he or she doesn’t have get Baptised again; they are already Christian. The Baptist tradition is Christian Baptism, the understanding of the Trinity is Christian.
As far as LDS, I think they seem to be outstanding as far as their voting habits generally. I believe they voted against Reid handily in NV against Angle.
