Yup, I'd even say in medieval period Poland was less christian than in 17th/18th century :) In 1500s at one point majority of nobility went protestant, and there was still a lot of orthodox nobles from Lithuania. Peasants were orthodox or pagan in the east, catholic in the west with some protestants, muslims and jews mixed in. In the cities there was a lot of german immigrants who were protestant or catholic depending on the city they immigrated from. Whole towns and villages were created by importing people from the west and giving them religious freedoms and tax benefits for a few years. By 1700s it was mostly gone, because the country kept fighting muslims, orthodox and protestant countries. So kings turned to catholicism and counter-reformation as uniting factor. So religion got a lot of influence.
