I help teach people from other faiths wanting to become full members of the Catholic Church. All of my RCIA students who are already baptized in the Name of the Trinity in any church, Baptist, Lutheran, Church of God in Christ, whatever --- are recognized as being already Christians, and --- in the incipient sense --- already Catholics.
For instance, my husband, who was baptized in the Baptist church, was recognized as being fully able to receive a Catholic sacrament, namely Matrimony.
The Catechism says:
Paragraph # 838 "Those who believe in Christ and have been properly baptized are put in a certain, although imperfect, communion with the Catholic Church." |

Thanks for your description of canon law (I presume thats what you mean) but I do remember a statement from some Catholic authority claiming Protestants were not real Christians (in the eyes of the church.)
