Similar to other Goan Brahmin temples, Ramnathi too incorporates the system of Panchayatan, therefore, this temple houses 5 main deities namely; Shri Ramnath (chief deity), Shanteri, Kamakshi, Laxmi Narayan, Ganapati, Betal and Kalbhairav, along with other family purushas.Local Hindus believe the Ramanath idol to have originally been installed by Rama at Rameshwar.
The Idol of Ramnathi was shifted to the present site in the 16th century to prevent its destruction by the then Portuguese colonizers.
[4] The kulavis or associated families had migrated out of Salsette due to religious persecution and now dwell all along the western coast of India.
A large number of the kulavis live in Goa, Mumbai, coastal Karnataka, Kerala and abroad.
[citation needed] The Ramanthi Temple is also visited by Gowd Saraswat Brahmins of other Gotras also.
