'First Church of Christ Scientist Rochdale'

There are churches called 'First church of Jesus Christ Scientist'. These are connected with what is known as Christian Science. Then there is also what is known as Scientology.

Catholic churches almost never use the label "Church of Christ," even though that is what they are. They avoid using this term only so as to avoid being confused with other denominations and communities of that or similar name already in existence, such as Churches of Christ; Independent Churches of Christ; International Churches of Christ; United Churches of Christ; United Churches of Christ, Congregational; Churches of Christ, Scientist; and Church of Christ, Instrumental. Catholic churces almost always have the word Catholic in their name.
