Each church is free to establish whatever form of organisation is suitable and useful itself, for God has prescribed nothing specific about this. - John Calvin

When we hear any mention of our mystical union with Christ, we should remember that holiness is the channel to do it.

The one condition for spiritual progress is that we remain sincere and humble. Let us keep our end in view, let us press forward to our goal. Let us not indulge in pride, nor give in to our sinful passions. Let us steadily exert ourselves to reach a higher degree of holiness till we shall finally arrive at a perfection of goodness which we seek and pursue as long as we live, but which we shall attain then only, when, freed from all earthly infirmity, we shall be admitted by God into his full communion.

There is also an old proverb, that they who pay much attention to the body generally neglect the soul.
