This is a question written in Latin that it means: Where do you go Master?
An ancient legend reports that when Saint Peters was escaping from Rome, for the pursuit to the christians, Jesus appeared to him in the way and Saint Peter, asked this question to him. After which Jesus answered him that he was going to Rome to be crucified for the second time. After this Saint Peter returned to Rome, where he was crucified.
What is the importance of this history?
Saint Peter in this history, is committing a lack, he is not acting with sufficiency, with demand.
To understand with more depth the topic, sometimes, when we have a problem the question is not if the solution is good or evil, but if the solution is sufficient or perfect itself.
How much times do we ask for Justice loudly and when we have Justice, it not satisfy anybody?
The Justice as such is an insufficiency.
When the "social evil" or the "common evil" abound, the golden rule, the spiritual gift of council, fails. The Charity itself turns into an insufficiency.
This is the problem that Saint Peter faces.
This is the deepest meaning of the question: Quo Vadis Domine?
Ethically opposite to the "social evil", we need a special spiritual gift: the Fervor.
Fervor means "ferment", it means to be motivated. But it is not this passing motivation that arises in spite of reading or listening to a good speech. It is a "top motivation", it is joined to the constancy, the firmness.
In a wide or general sense, the really successfull persons are provided with this perfection. "Motivation with constancy, firmness".
The motivation with constancy "grants" a special force in ours actions.
This is something prepers of the genuine leaders.
The fervor, from the ethical or spiritual point of view, is a spiritual gift that attends to the "correct social order" or to the "common good".
The fervor goes beyond the Hope, supports it. The common good and not simply the good, is only attainable for the existance of this spiritual gift. This article belongs to the ambience of the Axiological Philosophy.
