Certainly, Christianity has a logical expression contained in the Creed; but this is not separate from other manifestations. It also has a logical teaching, which we call theology. But this is only a branch of general teaching. To isolate it is a great error; to give it exclusive preference is madness; to see in it a heavenly gift tied to certain functions is a heresy. That would be to establish a sacrament of rationalism.
The Church does not recognize a teaching Church other than herself in her totality.
