The Journey of Life
It seems to be a common human desire to use ritual to mark important stages in life, and life-cycle rites tend to be found in most religions. Pagan rituals may include those for new babies, ‘handfasting’ for couples who want to publically acknowledge their partnership, and funerals. In addition, there may, especially in Goddess spirituality, be ceremonies to mark stages in women’s lives such as first menstruation and its cessation.
For those traditions that have different degrees or levels of attainment, there will be ceremonies to mark those stages. A local Pagan priestess commented that she is often called upon to celebrate weddings and welcome babies, even by those who do not call themselves Pagan, an attraction of a Pagan ceremony being that it can be customised to suit those involved.
