Relationship between villages of Lipiny and Redziny in Poland

In doing research within Pilzno Catholic church records, I noticed that many of my relatives who claimed to be from Lipiny were actually in the church records of Rędziny. When I looked these villages up, they have the same coordinates. Both names are being used during the same time frame but there is a definate division as far as church records go. Can anyone explain the relationship between these 2 villages?

From the information over internet I can conclude that Lipiny is a main town and Rędziny is just a part of this village.

Powiat -(pow) means that this is the regional centre of the villages.

Thank you so much for the explanation. Sites were very helpful.
