Using the Blake Concordance I found only two occurrences of the word, idol; it led me to two plates (60 and 61) in Jerusalem. Together they represent a central tenet of Blake's gospel; it concerns forgiveness:
Jerusalem, Plate 60:
"The clouds of Albions Druid Temples rage in the eastern heaven
While Los sat terrified beholding Albions Spectre who is Luvah
Spreading in bloody veins in torments over Europe & Asia;
Not yet formed but a wretched torment unformed & abyssal
In flaming fire; within the Furnaces the Divine Vision appeard
On Albions hills: often walking from the Furnaces in clouds
And flames among the Druid Temples & the Starry Wheels
Gatherd Jerusalems Children in his arms & bore them like
A Shepherd in the night of Albion which overspread all the Earth
I gave thee liberty and life O lovely Jerusalem
And thou hast bound me down upon the Stems of Vegetation
I gave thee Sheep-walks upon the Spanish Mountains Jerusalem
I gave thee Priams City and the Isles of Grecia lovely!
I gave thee Hand & Scofield & the Counties of Albion:
They spread forth like a lovely root into the Garden of God:
They were as Adam before me: united into One Man,
They stood in innocence & their skiey tent reachd over Asia
To Nimrods Tower to Ham & Canaan walking with Mizraim
Upon the Egyptian Nile, with solemn songs to Grecia
And sweet Hesperia even to Great Chaldea & Tesshina
Following thee as a Shepherd by the Four Rivers of Eden
Why wilt thou rend thyself apart, Jerusalem?
And build this Babylon & sacrifice in secret Groves,
Among the Gods of Asia: among the fountains of pitch & nitre
Therefore thy Mountains are become barren Jerusalem!
Thy Valleys, Plains of burning sand. thy Rivers: waters of death
Thy Villages die of the Famine and thy Cities
Beg bread from house to house, lovely Jerusalem
Why wilt thou deface thy beauty & the beauty of thy little-ones
To please thy Idols, in the pretended chastities of Uncircumcision[?]
Thy Sons are lovelier than Egypt or Assyria; wherefore
Dost thou blacken their beauty by a Secluded place of rest.
And a peculiar Tabernacle, to cut the integuments of beauty
Into veils of tears and sorrows O lovely Jerusalem!
They have perswaded thee to this, therefore their end shall come
And I will lead thee thro the Wilderness in shadow of my cloud
And in my love I will lead thee, lovely Shadow of Sleeping
This is the Song of the Lamb, sung by Slaves in evening time.
But Jerusalem faintly saw him, closd in the Dungeons of Babylon
Her Form was held by Beulahs Daughters. but all within unseen
She sat at the Mills, her hair unbound her feet naked
Cut with the flints: her tears run down, her reason grows like
The Wheel of Hand. incessant turning day & night without rest
Insane she raves upon the winds hoarse, inarticulate:
All night Vala hears. she triumphs in pride of holiness
To see Jerusalem deface her lineaments with bitter blows
Of despair. while the Satanic Holiness triumphd in Vala
In a Religion of Chastity & Uncircumcised Selfishness
Both of the Head & Heart & Loins, closd up in Moral Pride.
But the Divine Lamb stood beside Jerusalem. oft she saw
The lineaments Divine & oft the Voice heard, & oft she said:
O Lord & Saviour, have the Gods of the Heathen pierced thee?
Or hast thou been pierced in the House of thy Friends?
Art thou alive! & livest thou for-evermore? or art thou
Not: but a delusive shadow, a thought that liveth not.
Babel mocks saying, there is no God nor Son of God
That thou O Human Imagination, O Divine Body art all
A delusion. but I know thee O Lord when thou arisest upon
My weary eyes even in this dungeon & this iron mill.
The Stars of Albion cruel rise; thou bindest to sweet influences:
For thou also sufferest with me altho I behold thee not;
And altho I sin & blaspheme thy holy name, thou pitiest me;
Because thou knowest I am deluded by the turning mills.
And by these visions of pity & love because of Albions death.
Thus spake Jerusalem, & thus the Divine Voice replied.
Mild Shade of Man, pitiest thou these Visions of terror & woe!
Give forth thy pity & love. fear not! lo I am with thee always.
Only believe in me that I have power to raise from death
Thy Brother who Sleepeth in Albion: fear not trembling Shade"
Jerusalem, Plate 61:
"Behold : in the Visions of Elohim
Jehovah, behold Joseph & Mary And be comforted O Jerusalem
in the Visions of Jehovah Elohim
She looked & saw Joseph the Carpenter in Nazareth & Mary
His espoused Wife. And Mary said,
if thou put me away from thee
Dost thou not murder me?
Joseph spoke in anger & fury.
Should I Marry a Harlot or an Adulteress?
Mary answerd, Art thou more pure
Than thy Maker who forgiveth Sins & calls again Her that is Lost
Tho She hates. he calls her again in love. I love my dear Joseph
But he driveth me away from his presence. yet I hear the voice of God
In the voice of my Husband. tho he is angry for a moment,
he will not Utterly cast me away.
if I were pure, never could I taste the sweets
Of the Forgive[ne]ss of Sins! if I were holy! I never could behold the tears Of love!
of him who loves me in the midst of his anger in furnace of fire.
Ah my Mary: said Joseph: weeping over & embracing her closely in His arms:
Doth he forgive Jerusalem & not exact Purity from her who is
Polluted. I heard his voice in my sleep O his Angel in my dream:
Saying, Doth Jehovah Forgive a Debt only on condition that it shall Be Payed?
Doth he Forgive Pollution only on conditions of Purity
That Debt is not Forgiven! That Pollution is not Forgiven
Such is the Forgiveness of the Gods, the Moral Virtues of the
Heathen, whose tender Mercies are Cruelty. But Jehovahs
Salvation Is without Money & without Price,
the Continual Forgiveness of Sins
In the Perpetual Mutual Sacrifice in Great Eternity! for behold!
There is none that liveth & Sinneth not! And this is the Covenant
Of Jehovah: If you Forgive one-another, so shall Jehovah Forgive You:
That He Himself may Dwell among You.
Fear not then to take To thee Mary thy Wife,
or she is with Child by the Holy Ghost
Then Mary burst forth into a Song! she flowed like a River of
Many Streams in the arms of Joseph & gave forth her tears of joy
Like many waters, and Emanating into gardens & palaces upon
Euphrates & to forests & floods & animals wild & tame from
Gihon to Hiddekel, & to corn fields & villages & inhabitants
Upon Pison & Arnon & Jordan."
Here's what he thought of the establishment gospel:
"Priests in black gowns were walking their rounds,
And binding with briers my joys and desires" (from The Garden
of Love); Erdman 26)
And how like the famous Spectre:
"Seven of my sweet loves thy knife
Has bereaved of their life
Their marble tombs I built with tears
And with cold & shuddering fears
Seven more loves weep night & day
Round the tombs where my loves layt
And seven more loves attend each night
Around my couch with torches bright"
Blake worked with the Everlasting Gospel (Erdman 518-24) for years trying to explain how his gospel differed from the Establishment one; what came forth is (certainly not lucid), ambiguous, tortured English; the Spirit simply doesn't lend itself to our words. Here are the last few lines:
"The Vision of Christ that thou dost see
Is my Visions Greatest Enemy
Thine has a great hook nose like thine
Mine has a snub nose like to mine
Thine is the Friend of All Mankind
Mine speaks in parables to the Blind
Thine loves the same world that mine hates
Thy Heaven doors are my Hell Gates
Socrates taught what Melitus Loathd as a Nations bitterest Curse
And Caiphas was in his own Mind
A benefactor of Manking
Both read the Bible day & night
But thou readst black where I read white"
Reading it 'white' is what all true Blakeans strive to do.
