The most unpardonable sin in society is independence of thought.

The unpardonable sin, in Campbell’s book, was the sin of inadvertence, of not being alert, not quite awake.

Ignorance is not innocence but sin.

To wish to withstand the Holy Spirit would be the one unforgivable sin.

Knowledge forbidden?
Suspicious, reasonless. Why should their Lord
Envy them that? Can it be a sin to know?
Can it be death?

Now listen to me, Buddy: there is only one unpardonable sin - deliberate cruelty. All else can be forgiven. That, never.

The Church no longer contends that knowledge is in itself sinful, though it did so in its palmy days; but the acquisition of knowledge, even though not sinful, is dangerous, since it may lead to pride of intellect, and hence to a questioning of the Christian dogma.

I still think sincere pessimism the unpardonable sin.

Faith: not wanting to know what the truth is.

nothing is so displeasing to God as an impenitent heart. Impenitence is the one sin for which there is no forgiveness.

Self-rejection is the biggest sin that you commit

Every other knowledge is harmful to him who does not have knowledge of goodness.

Sin is whatever obscures the soul.

How dreadful the knowledge of the truth can be
When there’s no help in truth.
