A "Borromean cross", which contains four Borromean rings configurations arranged in a cross shape.  This means that no two circles are directly interlinked, and cutting the central loop frees the other four circles.
This could be interpreted as a Christian symbol, since it combines the cross with the Borromean rings (often used as a symbol of the Christian Trinity).  However, a similar design (not Borromeanly-linked) is found as a Japanese mon in Handbook of Design and Motifs (1950), and may be occasionally used as a neo-pagan "five worlds" symbol...
