Well I guess that depends what you mean by 'beliefs'. The Church has one mind (the mind of Christ). It has one Faith, one baptism, one Lord of all...
If you mean by church the individual believers, then the individual believers have beliefs, and some may be correctly formed, and some may be misguided, and in error.
If you mean the church as an institution, that is, the corporate body of believers as a unit, then, well, let's look at the passage.
Ephesians 4
4 There is one body, and one Spirit, even as ye are called in one hope of your calling;
5 One Lord, one faith, one baptism,
6 One God and Father of all, who is above all, and through all, and in you all.
7 But unto every one of us is given grace according to the measure of the gift of Christ.
One body, so we are a unit. One Spirit, this is what unifies us. One expectation, we serve One Lord, there is a single faith - one faith - that is true. On baptism with which we are baptized. One God and Father.
Continuing on . . .
11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
So then not all are in the unity of the faith and of the knowledge of the Son of God.
So if we are not all in unity faith and knowledge, how would we be able to say that the corporate body of Christ has a belief? We have various beliefs, and we need to all be brought together into maturity, when we will go on from that unity to build each other up in love.
All are in communion with a community founded by an apostle? Surely not...
That would be the Body of Christ. So we are to divide by those who name an apostle? I am in the body of Christ, founded by Christ, and built upon by the Apostles. Is this not true of all who are born again?
Much love!
