The Parish of St. Stanislaus in Sarnaki has a long and rich history, dating back to around 1430, when the first wooden church was built. Over time, due to its poor condition, it was demolished in 1816, and a new, also wooden, church was built on the opposite side of the road by the estate owner, Count Stanisław Ossoliński. Throughout its existence, the church has been renovated many times, with significant restoration work carried out in 1905. The parish has belonged to various dioceses, starting from the Diocese of Brześć, then the Podlasie Diocese, the Lublin Diocese, and finally the Siedlce Diocese. In 1992, Pope John Paul II incorporated the Sarnaki parish into the Drohiczyn Diocese, which had a significant impact on the local community.
The current church, built in a neo-Baroque style with elements of Vilnius Renaissance, began construction in 2012 and was completed in 2020. This was a particularly important event in the context of local culture and tradition, despite the limitations caused by the COVID-19 pandemic. From a historical perspective, the parish has witnessed many transformations, and its boundaries have changed over the centuries, encompassing many surrounding localities. Today, the parish includes towns such as Sarnaki, Binduga, Chlebczyn, and Grzybów, highlighting its importance in the region.
An interesting fact is that the old church, which currently serves auxiliary functions, is soon to be relocated to another site. The parish, along with the new church, plays an important role in the life of the local community, preserving traditions and supporting the spiritual development of its residents.
