What is the Purpose of Sacred Vestments?

Solemn Mass at the Abbey of Saint Madeleine,
Le Barroux.

If we were to accept the notion that a priest is the "president of the christian assembly" then what he wears to celebrate the Sacred Liturgy would be merely an expression of his personality or tastes. The notion of presider is an entirely modern (and an execrable) concept. A priest, bishop or Pope celebrates the Sacred Mysteries. In the East, the term used is to serve.

Because the celebrant is least of all a "presider", what he wears is not about his own preferences and personality. A priest should ask of himself :

Is what I am wearing worthy of my ministry standing between God and man to offer the Holy Sacrifice?

Will what I am wearing draw those who look upon me during Mass into a closer appreciation of the Sacred Mysteries, in other words, will it raise their hearts and minds to God?

Or will it act as a distraction to the Faithful attending Mass?
