The Constitution of Societas Rosicruciana in Lusitania (SRIL) took place on October 5, 2002, in the Church of Santiago in Palmela Castle sponsored by Societas Rosicruciana in Civitatibus Foederatis, based in the United States of North America; and with the support of Societas Rosicruciana in Galia, since dissolved, France being now a Province of Societas Rosicruciana in Anglia based in England.

SRIL provides its members (fratres) with the structure, direction, and resources for their enlightenment and progress in the knowledge of the great Problems of Life, and in the discovery of the Secrets of Nature; to facilitate the study of the System of Philosophy based upon the Kabbalah and the doctrines of Hermes Trismegistus, which was inculcated in the original Rosicrucian texts, in order to better understand and appreciate their relationship to Man and his Creator.

The goal of SRIL is that its members, collectively and reciprocally, learn the meaning and symbolism of the entire heritage of Wisdom, Arts, and Literature, and contribute to unraveling the great questions of Creation, through the system of Rose-Cross Philosophy, in order to better understand the meaning of their existence and contribute to a better World.
