There are no data about Földes's ecclesiastical life in the Middle Ages.
Földes, before the Reformation, belonged to the Diocese of Eger along with the neighboring villages of Szabolcs County.
In the second half of the 16th century, after 1557, the inhabitants of the village converted to the Reformed faith when the Reformed Church had finally been established and consolidated in Debrecen.
After the Reformation, Földes was a part of the Reformed Diocese of Debrecen.
The first reliable data can be found in 1597 about the existence of the Földes Reformed Church.
At that time, the Debrecen Council ruled on the divorce case of a pastor named Mihály from Földes and declared the husband guilty in the divorce lawsuit, not allowing him to divorce from his wife.

Temple building and tower
In 1621, there was temple but there were only a small number of people of the Földes Church because it had only a pastor but not a rector or teacher.
Even so, the Church of Földes was a Mother Church and Tetétlen as a Daughter Church (filialis) without temple was attached to it.
In 1713, a bell tower was built, near the temple building.
In 1769 the church building was enlarged and in 1770 the bell tower was raised.
The church building was extended from 10 fathoms to 11 and a half fathoms and the width from 3 fathoms to 6 fathoms.
The bell tower was raised from 10 fathoms to 11 fathoms and the width remained 10 fathoms.
The extension of the old church building was necessary, because it had only 383 places for 1,073 believers and 690 people were left outside.
In 1818, the number of believers was 3,000 and the number of places in the church building was again low.
In the same year, a lightning struck the tower and the church building, and the damages had to be repaired.
Between 1822–28, the building of the church was extended from 11 and a half fathoms to 18 and a half fathoms.
Between 1830–34 the bell tower was built together with the church building and raised from 11 fathoms to 21 fathoms high.
The next enlargement was taken place in 1884.
At that time the number of Calvinist believers was 4,384.
In 1910, the wooden beam bearing the tower ball and tower star on top of the tower had to be replaced.
Then the church was repaired in the 1930s, 1970s and 1990s.
In 2004, the wooden beam that had been put up into the tower in 1910 and it had held the tower ball and star, it had been broken and it was exchanged.
The last repair was in 2010 when the floor of the church was changed for brick coverage.

Bells
The bell tower was built in 1713.
In 1770 when the bell tower was being raised, two bells were removed from the old tower and then placed in the new tower.
One of the bells was made in 1744 and the other was made in 1758 and each had a weight of 3 Vienna centner (168 kilograms).
These bells were replaced in 1868 with 3 new bells.
The new bells were made by Ignácz Hilzer in Bécsújhely and were put up into the tower by József Pozdeck Budapest.
The big bell 16 Vc (907 kg) and the middle bell 9 Vc (528 kg) were taken to war in 1917.
Instead them, the Church had two new bells made in 1923.
The new big bell was 855 kg and the new middle bell was 517 kg and have remained until today.
The 283 kg small bell made in 1868, it had been cracked and was replaced in 1998 by a 260 kg bell had been made by Lajos Gombos in Őrbottyán.

Tower Clock
The village had it made in 1778 and commissioned György Földessy, a clock master, to care for the tower clock and paid for it.

In 1870, the clock machine was amended with a quarter-hour instrument by Sándor Körvélyessy clock master and Ferencz Körtvélyessy smith master.
In the cost of the 450 Forints modification, the Földes Jewish residents provided 40 Forints.

Church Organ
The first donation for the building of the church organ was donated by Gábor Sápy and his wife, Eszter Szabó, in 1884, with 10 pieces of Körmöc gold.
The donations were assembled by the intervention of pastor Ferenc Kiss, and in 1894 the church organ was made by József Angster a Pécs organ builder.
