Religion's Meaning when I would recall,
Love is to me the plainest Word of all.
Plainest, — because that what I love, or hate,
Shews me directly my internal State;
By its own Consciousness is best defin'd
Which way the Heart within me stands inclin'd. On what it lets its Inclination rest,
To that its real Worship is address'd;
Whatever Forms or Ceremonies spring
From Custom's Force, there lies the real Thing;
Jew, Turk or Christian be the Lover's Name,
If same the Love, Religion is the same.
