I’ll give you an example.
The Catholic Church and the Oriental Orthodox Church finally settled their differences on the matter of the Natures of Christ.
Both Churches, in humility, without asking the other to give up their theology (i.e., their respective expressions of the common Faith), proferred the question: “What are we trying to teach by our different expressions of Faith?” First you must understand that the stark difference between the Oriental Orthodox expression of Faith (i.e., theology) and the Catholic expression of Faith (i.e. theology) is:
- Oriental Orthodox teach and believe that Jesus Christ is OF two natures.
- Catholics teach and believe that Jesus Christ is IN two natures.
Oriental Orthodox traditionally believed that the Catholics were denying the hypostatic union because the statement “IN two natures” implies that there is no true union of the human and divine natures.
On the other hand, the Catholics traditionally believed that the OO were denying the hypostatic union because the statement “OF two natures” implies that when the union occurs, one of the natures is completely subsumed in or demolished by the other Nature (there was an actual heresy that taught this - Eutychianism - but it was not what the OO teach/believe)…
It has taken 1500 years to understand that neither the OO nor the Catholics teach and believe what one THOUGHT the other taught and believed just because of the
mere implications of the respective theological languages.
So the OO and the Catholic Churches have come out with joint declarations affirming the common Faith of both Churches that the Son is fully human and fully divine, and that the two natures are united without confusion, diminution, etc. of the two natures. And this was done without either Church having to let go of their respective theologies (i.e., expressions of the Faith).
