The child arrived with three envelopes from the distraught parents. One contained personal jewellery, another contained letters to relatives in Canada and the US, who were asked to take the boy if the Hillers should die. The third contained a letter to Mrs Yachowitz, a note to little Shachne, and their will.
The letter to Shachne explained how much they loved him, because of which they had given him up to another couple. They told him of his Jewishness, and that they hoped he would grow up to be proud of his heritage. The letter to the couple praised them for their actions, and pleaded: "If we should not survive this madness, raise our son as a Jew."
Sadly, the boy's parents did not survive the Holocaust. When the war ended, Mrs Yachowitz did not post the letters to the boy's relatives in Canada and the US. Instead, she waited a further year, then sought to have the boy baptised and formally raised as a Catholic. She went to the newly-ordained curate in her parish who had a reputation for being wise, compassionate and trustworthy.
She told him about the boy's identity, but not about the letter hand-delivered to her husband and herself.
The young priest listened intently, and asked: "What were the parents' wishes when they entrusted him to you?" Mrs Yachowitz blurted out the full story.
The priest told Mrs Yachowitz it would be unfair to baptise the child while there was still hope that the relatives of the child might take him. He declined to perform the ceremony.
In October 1978... Mrs Yachowitz, who was near death... revealed for the first time her bid to have [the boy] raised as a Catholic, and the reaction of the priest who had counselled her.
She disclosed the young priest's name - Karol Wojtyla, elected that month as Pope John Paul II.
