It is used a lot to enhance charisma. in some ways, it's a bit like religious people wearing modest clothes, and yet seeking the most expensive trends, to enhance appearances. Defeats the purpose.
The cross jewelry can be seen as both; indeed a monks Habit can be seen as both. I've said the same thing here so often it will drive people crazy. But then this is a column for Religion and Philosophy.
Cross jewelry can be fashion and as such associated with the things of this world. But again it can also be used for good. With a knife we can stab others, or we can use it to peel fruits. Brings me to what I wish to say.
The spiritual life is an inner journey, and the true experience happens in the Heart and Soul. The cross can and does act as a catalyst for those who seek God; who feels a burning intensity for Truth, for an abiding satisfaction.
It really is an inner journey, and motive and purity of intent, is of paramount importance. This can be lacking with the fashionistas, but never with the devout. Much Love, Brinafr.
