As the Dutch Reformed church in this country is an exact counterpart of the church of Holland, so the German Reformed is of the Reformed or Calvinistic church of Germany. The people of this persuasion were among the early settlers of Pennsylvania: here their churches were first formed; but they are now to be found in nearly all the states south and west of the one above named. The German Reformed churches in this country remained in a scattered and neglected state until 1746, when the Rev. Michael Schlatter, who was sent from Europe for the purpose, collected them together, and put their concerns in a more prosperous train. They have since increased to a numerous body, and are assuming an important stand among the American Presbyterians.

This denomination is scattered over the Middle, Western, and Southern States, but is most numerous in the states of Ohio and Pennsylvania. The population of this church in the United States is estimated at 300,000; 180 ministers, 600 congregations, and 30,000 communicants.
