Angels are spirits, but it is not because they are spirits that they are angels. They become angels when they are sent. For the name angel refers to their office, not their nature. You ask the name of this nature, it is spirit; you ask its office, it is that of an Angel, which is a messenger.
O Lord my God,
tell me what you are to me.
Say to my soul,
I am your salvation.
Say it so that I can hear it.
My heart is listening, Lord;
open the ears of my heart
and say to my soul,
I am your salvation.
Let me run toward this voice
and seize hold of you.
Do not hide your face from me:
let me die so that I may see it,
for not to see it would be death to me indeed.
It is indeed better (as no one ever could deny) that men should be led to worship God by teaching, than that they should be driven to it by fear of punishment or pain; but it does not follow that because the former course produces the better men, therefore those who do not yield to it should be neglected. For many have found advantage (as we have proved, and are daily proving by actual experiment), in being first compelled by fear or pain, so that they might afterwards be influenced by teaching, or might follow out in act what they had already learned in word.
The measure of charity may be taken from the want of desires. As desires diminish in the soul, charity increases in it; and when it no longer feels any desire, then it possesses perfect charity.
When all is said and done, is there any more wonderful sight, any moment when man's reason is nearer to some sort of contact with the nature of the world than the sowing of seeds, the planting of cuttings, the transplanting of shrubs or the grafting of slips?
Who else is it who calls us back from the death of error, except the life that does not know death, and the wisdom which, needing no light, enlightens minds which are in darkness, that wisdom by which the whole world, even to the leaves of trees drifting in the wind, is governed?
