“If religion consists in external regulations and observances, it is two things. It is far too easy. It is very much easier to abstain from certain foods and to wash the hands in a certain way than it is to love the unlovely and the unlovable, and to help the needy at the cost of one’s own time and money and comfort and pleasure.” - William Barclay
