Of the five basic symbols, the cross is unique in that it is the only one in which two points or elements intersect. It commonly symbolizes relationships. In Christianity, for example, the cross represents Christ as the connection between mortal man and God the Father. As the World Tree or Tree of Life symbol, the cross represents the connection between heaven and earth. As the Native American Medicine Wheel, it represents creating order and balance between the four directions: North, South, East and West, and as the Indo-European Sun Cross, it represents the balance between the four elements, found at the core of Neopagan practices. In West African religions, these intersections take the form of a crossroads as a powerful physical space.

A popular variation of the cross motif is the combination of the circle and the cross. The neolithic cross, which was later adapted into the Celtic cross, and the Sun Cross are two examples of this. The sun cross is best known as the Native American medicine wheel and as a symbol of neopagan beliefs. It has also notably been seen throughout Europe since the neolithic era, and was adopted by Bulgarian Tzars as a symbol of the Bulgarian Orthodox Church in early Christian history. The cross within a circle also appears as the cruciform halo worn by Christ in medieval art, as well as in some images of the World Tree, an important motif used to represent many cultures' spiritualities and mythology around the world. This world tree, or tree of life, is recognized primarily in Indo-European, Siberian, and Native American religions. The ankh, an ancient Egyptian symbol predating the Christian cross, represents fertility and life -primarily eternal life.

Even as the cross has a universal meaning that spans across cultures worldwide, it can represent many different things depending on its context. Depending on ones cultural heritage, it can represent life, fertility, perseverance and endurance, self sacrifice, protection, bravery, martyrdom or memorial, heroism, heraldry, or the balance of life and its elements.
