All towns in the Commonwealth are required to have an official seal. The seal is used by the Town Clerk in the form of an embosser to notarize certain official documents coming from the town. In 1980, Natick Town Meeting voted to make a new official seal from an image that was created by a town resident in 1951. Currently, the embosser the town uses has a simplified version of this officially adopted imagery. Below is the image the embosser makes, as well as a digital image of the seal that is used on the town website and has been variously modified by many town departments.
The official seal depicts, in the center, an image of John Elliot preaching to Indigenous peoples with the years of Natick's founding and incorporation surrounding it; this image is placed atop an image of a bible with a tree protruding from the top with the text "Natick" and "Massachusetts" draped at the top and bottom of the image (note the latter details is not incorporated on the official embosser).
The official seal, embosser, and department logos should be consistent, although they currently are not.
