Isabelle Romée

Dominant Si lives by what is settled, tested, and known. Isabelle's religion was not a position she had reasoned her way into but a foundation she had stood on her whole life — the faith of her village, her parish, the road she had once walked to Rome. She passed it to Joan not as argument but as inheritance: the prayers, the saints, the certainty that God was near and could be trusted. That depth of settled belief is exactly the soil from which Joan's own conviction grew.

The same function explains the most remarkable thing about her. Si does not forget, and it does not let go. For twenty-five years Isabelle held the memory of her daughter and her certainty about her daughter's innocence intact, unbroken, against the official judgment of the Church and the weight of every passing year. Where another temperament might have been worn down by time, grief, or hopelessness, Si simply endured — the same truth held steady, day after day, until the day she could finally act on it.

Her perseverance was not the restless drive of someone seeking a new outcome; it was the patience of someone who already knew the truth and was waiting, dutifully, for the world to catch up to it. That is Si's particular kind of strength: not momentum but constancy.

If Si gave Isabelle her constancy, auxiliary Fe gave it its object and its warmth. Everything she did, she did for her daughter. Her cause was never an abstraction — not justice in general, not the reputation of the Church, not a point of canon law — but one specific child, loved beyond reason, whose name had been disgraced. Fe orients toward people and bonds, and Isabelle's entire campaign was the long expression of a single bond that death had not severed.

In 1455 that devotion carried a frail old woman to Notre-Dame de Paris to stand before the delegates of the Pope and ask, in person, that her daughter's case be reopened. The accounts describe her plea as moving precisely because it was not a legal argument but a mother's — grief and love made audible before the highest authorities of the Church. Fe knows how to reach a room, how to make others feel what the speaker feels, and Isabelle's appeal worked: it launched the nullification trial of 1455–56.

That she could marshal such warmth and bring it before princes of the Church without flinching is the auxiliary doing its work — turning a private, grieving woman into a public, effective advocate, not for power or principle, but for love.

Tertiary Ti in an ISFJ is modest and practical rather than systematizing, but Isabelle's long fight was not pure feeling — it had a thread of cold accuracy running through it. She understood, however dimly the records let us see it, that the 1431 trial had been a travesty: a frightened girl tried by her enemies, condemned on a verdict that would not hold up if examined honestly. Her conviction that the judgment was wrong was not only love but a kind of clear-eyed correctness about what had actually happened.

That tertiary clarity is why her grief became a petition rather than merely a sorrow. She did not simply want sympathy; she wanted the verdict overturned, the record corrected, the error undone — a concrete, almost legal aim that an old peasant woman had no obvious right to pursue, and pursued anyway. Ti gave her cause its spine: not just that her daughter was loved, but that her daughter had been wronged, and that the wrong could be named and reversed.

Inferior Ne is the least-developed corner of the ISFJ, and Isabelle's life was lived largely within the small, known horizon Si prefers — one village, one parish, one familiar round of seasons and prayers. The wider world of possibility, of imagined futures and untried paths, was not her native country. She was not a strategist or a dreamer of outcomes; she was a woman who knew one thing and held it.

And yet inferior functions surface under pressure, sometimes heroically. The pilgrimage to Rome that gave her her name was one reach beyond the village; the journey to Notre-Dame de Paris in old age was another. To leave the known world and carry a hopeless-seeming cause to the center of Church power required imagining that things could be otherwise — that a settled verdict might be unmade, that an old peasant woman's plea might move the machinery of Rome. For an inferior-Ne type, that leap into open possibility was no small act. It was love forcing the weakest function awake, and it worked.

Why ISFJ Over ISTJ

The distinction is the whole of her story. Both types could have persevered for twenty-five years; what mattered is what the perseverance was for. An ISTJ's long campaign would have been austere, principled, institution-bound — the righting of a wrong because wrongs ought to be righted. Isabelle's was tender and particular: a mother who could not rest while her daughter's name lay in disgrace, and whose love, not her sense of order, carried her to Notre-Dame. The ISFJ perseveres because she loves; the ISTJ perseveres because she must. Isabelle loved.
