Thalwil is one of the oldest parishes on the shores of Lake Zurich.
It also has one of the most spectacular church locations, with the Platte affording views of the lake and its surroundings from Zurich to the Alps.

The earliest recorded church was dedicated to St Martin in 1159.
In medieval times it was a dependency of Wettingen Abbey.
Although it was frequently hit by lightning and also looted and set on fire during the Old Zürich War (Alter Zürichkrieg), the original building survived for over six hundred years.

In 1845 the small and rather dilapidated chapel was demolished and replaced by a much larger church designed by Ferdinand Stadler.
A fire set off during repairs on the tower burnt down the new church  almost 100 years later (1943) but the building was soon completely restored and has survived to this day.

As of 2008 there were 5382 Catholics and 5881 Protestants in Thalwil.
 In the 2000 census, religion was broken down into several smaller categories.
 From the census, 41.5% were some type of Protestant, with 39.3% belonging to the Swiss Reformed Church and 2.2% belonging to other Protestant churches.
 34.3% of the population were Catholic.
 Of the rest of the population, 3.8% were Muslim, 5.8% belonged to another religion (not listed), 2.6% did not give a religion, and 15% were atheist or agnostic.
