Is that statement not a contradiction?
For men, A cannot be not A...for God, I don’t know.
Does that also mean the beginning cannot be the end?
Now ... since you acknowledge non-contradiction, you must also acknowledge the singularity of truth. With the singularity of truth in mind, let's revisit that paragraph about sinful pride:
Pride - The sinful drive that distorts proper self love so that we esteem ourself more than is proper and at the same time denigrate the goodness of others. There is such a thing as well ordered self love and self esteem but Pride is love of self which is perverted causes us unjustly to think of others as beneath us or less worthy. Pride also stirs us to reject lawful authority of others over us including God and refuses appropriate submission. Pride is at the root of every sin for through it we pridefully think we have a way better than what God has set forth or that we alone can be the judge of right and wrong. Adam and Eve wanted to “be like Gods” and wanted themselves to determine what was right and wrong. Hence they demanded to eat of the tree of the “Knowledge of good and evil.” This is Pride.
we esteem ourself more than is proper ... Do you see any correlation between the singular truth about oneself, and the degree to which one esteems oneself?
at the same time denigrate the goodness of others Do you see any correlation between the singular truth about another, and the degree to which one passes judgment on that other's goodness?
Do you understand that actually knowing the entire truth about oneself, or about others, borders on impossible? Do you think, perhaps, that judgments passed on oneself or others, based on an incomplete knowledge of the truth might perhaps best be tempered in accordance with that lack of knowledge?
