"Confession of sins and transgressions before human beings is not permissible ..."

"The eighth Glad-Tidings
The pious deeds of the monks and priests among the followers of the Spirit (Jesus) —upon Him be the peace of God— are remembered in His presence. In this Day, however, let them give up the life of seclusion and direct their steps towards the open world and busy themselves with that which will profit themselves and others. We have granted them leave to enter into wedlock that they may bring forth one who will make mention of God, the Lord of the seen and the unseen, the Lord of the Exalted Throne.

The ninth Glad-Tidings
When the sinner findeth himself wholly detached and freed from all save God, he should beg forgiveness and pardon from Him. Confession of sins and transgressions before human beings is not permissible, as it hath never been nor will ever be conducive to divine forgiveness. Moreover such confession before people results in one’s humiliation and abasement, and God—exalted be His glory—wisheth not the humiliation of His servants. Verily He is the Compassionate, the Merciful. The sinner should, between himself and God, implore mercy from the Ocean of mercy, beg forgiveness from the Heaven of generosity and say:

O God, my God! I implore Thee by the blood of Thy true lovers who were so enraptured by Thy sweet utterance that they hastened unto the Pinnacle of Glory, the site of the most glorious martyrdom, and I beseech Thee by the mysteries which lie enshrined in Thy knowledge and by 25 the pearls that are treasured in the ocean of Thy bounty to grant forgiveness unto me and unto my father and my mother. Of those who show forth mercy, Thou art in truth the Most Merciful. No God is there but Thee, the Ever-Forgiving, the All-Bountiful.

O Lord! Thou seest this essence of sinfulness turning unto the ocean of Thy favour and this feeble one seeking the kingdom of Thy divine power and this poor creature inclining himself towards the day-star of Thy wealth. By Thy mercy and Thy grace, disappoint him not, O Lord, nor debar him from the revelations of Thy bounty in Thy days, nor cast him away from Thy door which Thou hast opened wide to all that dwell in Thy heaven and on Thine earth.

Alas! Alas! My sins have prevented me from approaching the Court of Thy holiness and my trespasses have caused me to stray far from the Tabernacle of Thy majesty. I have committed that which Thou didst forbid me to do and have put away what Thou didst order me to observe.

I pray Thee by Him Who is the sovereign Lord of Names to write down for me with the Pen of Thy bounty that which will enable me to draw nigh unto Thee and will purge me from my trespasses which have intervened between me and Thy forgiveness and Thy pardon.
Verily, Thou art the Potent, the Bountiful. No God is there but Thee, the Mighty, the Gracious."
