Feeney was disciplined for claiming that only formal members of the Church could be saved. The idea that only formal members of the Catholic Church could be saved was a misrepresentation of Extra Ecclesiam Nulla Salus and is not the teaching of the Church. The Church teaches that those who die in a state of sanctifying grace go to heaven. The question then becomes, how do those who are not formal members of the Church by sacramental baptism obtain sanctifying grace initially or if it has been lost by mortal sin.
Remember, the Church teaches that any baptism by water in the Name of the Father, Son, and Holy Spirit is a valid sacramental baptism, makes one a member of the Church, and confers sanctifying grace and is cause for the remission of Original Sin and personal sin.
The Church also teaches baptism by desire and baptism by blood. It is by an elastic interpretation of baptism by desire that many ecumenical types have claimed that there might be salvation outside the Church.
"If you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised Jesus from the dead, you will be saved. With the heart man believes unto righteouness and with the mouth confession is made unto salvation." Romans 10:9,10 This can be done anywhere, even on a bar stool in a saloon. Catholicism is bankrupt apostasy at its best.
