The Satanic Temple (TST) provides a number of services to its members through the activities of its congregations, campaigns, and ordained Satanic Ministry. The official TST website has a page that summarizes many of these services: https://thesatanictemple.com/pages/member-services
When you sign up as a member, you are added to The Satanic Temple’s newsletter and will receive regular updates, news, and announcements. Apart from that, however, the benefits that our members receive depend on how they choose to participate, and what they are looking to get from their involvement in TST.
For many of our members, the most salient and permanent benefit they get from joining The Satanic Temple comes in the form of connection, community, and a sense of shared purpose. To see if TST can provide that for you, dive in and start getting involved!
