Excellent!
The church is the body of believers. The body of Christ. Made up of all born again saved Christians.
It is NOT the Catholic church being noted in that scripture.
If my brother won't listen to the Seventh Day Adventists, should I treat him as a pagan or tax collector?
If my brother won't listen to the Presbyterians, should I treat him as a pagan or tax collector?
If my brother won't listen to the Baptists, should I treat him as a pagan or tax collector?
If my brother won't listen to the Lutherans, should I treat him as a pagan or tax collector?
If my brother won't listen to the Fundamentalists, should I treat him as a pagan or tax collector?
Are any of these "the church" that Christ founded? If not, why should I listen to them?
Not only do these churches contradict each other, they have all contradicted themselves over time. Only the Catholic Church possesses a non-contradictory body of Teaching, and the Authority given by Christ to teach authoritatively.
