Spiritism is at the same time a Science, a Philosophy and Religion.

Spiritism is a science because it studies the origin, nature and the destiny of the Spirits as well as its relationship with the corporeal world. Just as the telescope discovered the world of the infinitely large and the microscope discovered the world of the infinitely small, the Mediums were the means by which the spiritual world was discovered.
Although the fundamental principles of Spiritism has been taught throughout the ages it was formally born in April 18 1857 with the publication of the Spirits' Book resulting from meticulous studies of Allan Kardec on the spiritual phenomenon that was occurring throughout Europe and the US in the 1850s.

Allan Kardec used the scientific method to investigate the communications received from more than a thousand mediums. The conclusions of his observations as well as the answers he received from the Spirits on fundamental questions of life were compiled together in the Spirits' Book. Because Allan Kardec used the scientific method to prove the existence of life after death, which is a fundamental principle of any religion, Spiritism was able to marry Science and Religion.

Spiritism is also a philosophy because it answers the main questions we all have in life: Who are we? Where we came from? And where are we going? Most importantly it gives us a profound logical answer to what is the meaning and aim of our lives. By helping individuals understand their position and objective in the latter of evolution Spiritism provides the means not only to cope with great suffering but as well as it gives an insightful explanation of our purpose on Earth.

Finally, is Spiritism a Religion? Spiritism is also a Religion but not a Religion in the general understanding of what Religion stands for. Religion is usually associated with rituals of all sorts such as, worshipping with singing, prayers in a specific physical position, lighting of candles and incense, hierarchy of commands based on a central figure, devotions to spiritual entities represented in statues, money collection and so on... In that sense Spiritism is not a Religion because it doesn't have any rituals. Nonetheless Spiritism is a religion according to the original definition of the word religion, which is to connect the creature with the creator. Spiritism is a Religion because it has the foundation of all Religions; the existence of God, the immortality of the soul, the consequences of our actions. Spiritism is a Religion because it brings back the Moral Teachings of Jesus Christ free from allegory and dubious interpretations. Finally Spiritism is a Religion mainly because it leads individuals to better themselves thus connecting them with the Creator which is the pursuit of all Religions.
