The Reformed Church of Montgomery was founded mainly by the German element in 1732. As the population increased divisions arose in this church and several other churches were formed from it. The first house of worship was a log structure built in 1732. And it is said that the entrance of this old church was by means of a ladder placed on the outside. All these early records were kept in the Dutch language, and the services were also conducted in Dutch for the first fifty years. Then for a time each alternate Sunday the English language was used. Rev. John Michael Kern seems to have been the first settled pastor. He came in 1772 and resigned in 1776. Rev. G. W. Mancius, of the old parent Kingston Dutch Church, had been acting as a supply previous to that date, until his death in 1762. Three different church buildings have occupied the site since the old block house was taken down in 1760. The first was a frame structure erected immediately thereafter. The church contained sixty-eight pews, forty-six of which were occupied at a rental of 96L 8S. Pews for the elders and deacons were on the right and left of the old-fashioned pulpit. Among the names of the pew-holders are found those of Rockefeller, Youngblood, Mould, Decker, Weller, Robinson, etc., ancestors of many well-known families. The modern name of the church for years has been "the Brick Church of Montgomery." The present pastor is Peter Crispell.

The St. Andrew's Church at Walden, before alluded to, is another ancient religious society. This people passed through a troublous {sic} existence during the Revolution, and the parish was left vacant for some years until 1790. Finally, after emerging from a heavy debt, a new church was erected in the village of Walden in 1827. Then after many changes in rectors, another new church was decided upon in 1870. This with the parsonage cost $18,000, and in 1880 the church was finally consecrated free from debt.

The Reformed Presbyterian Church of Coldenham was organized in 1795, and a house of worship built four years later. This was replaced by a new structure in 1838. Dr. Alexander McLeod was the pastor from 1800 to 1812. The present pastor, Rev. Thomas Patton, was installed in 1893.

The Reformed Dutch Church of Berea, which came as a secession from the Goodwill Church, got its first pastor in 1823, Rev. James Ten Eyck, the congregation having been incorporated two years before. When the first little church was built it was surrounded by a forest, the timber for the building being cut from the site itself.

The First Reformed Church of Walden was incorporated in 1870, although the society was formed forty years before, and the church building was completed in 1838 at a cost of $12,000. Some $5,000 more was afterward spent upon the parsonage. Rev. M. V. Schoonmaker was the minister from 1849 to 1888. The present minister, Rev. W. W. Schomp, was installed in 1897.

The First Presbyterian Church of Montgomery was incorporated in 1832 and Rev. James O. Stokes was the first pastor. There were many changes in this pastorate in the succeeding years, and the debt piled up gradually until it reached $2,300 in 1848, a parsonage having been built meanwhile. This debt was, however, fully met that year under the pastorate of Rev. E. R. Fairchild, whose health soon failed, however. Rev. J. C. Forsyth was installed in 1875 and he continued in that field for many years.

The Methodist Church of Montgomery, was organized in 1829 with Rev. B. Howe and J. W. Lefever as priests. The "table expenses" of Mr. Howe were $100 and those of Lefever $50, which was in addition to the disciplinary allowance. A small church was built that year and a parsonage four years later.

In 1906 an Episcopal mission was established in Montgomery.

The Walden Methodist Church was incorporated in 1850. Previous to that the "classes" there were under the pastoral care of the Montgomery preachers. In fact, it was not until 1866 that the Walden Church became an independent charge. Then a parsonage was built and the church building was enlarged and improved in 1870 at a cost of $6,000. In 1893 it was removed to the east side of the church lot and remodeled.
