I have read the official biography several times. Alessandro Serenelli himself contributed greatly to it. Maria was a 12 year old girl who was quite developed physically for her age. 18 Year old Serenelli had been perusing pornographic material, which Maria was aware of, and noticed Maria’s blossoming for some time. On numerous occasions, he had attempted to seduce her to have sexual relations with him. He had also threatened her if she said anything. She was, quite honestly, afraid of him. She also did not want to create problems with her mother’s work relationship with the Serenelli’s, who were good hardworking people that made it possible for the Goretti family to be able to provide for themselves.
Maria repeatedly rebuffed Alessandro, which only made him more determined. It is the fact that she would not consent to his impure desires that she became a patron of purity. Serenelli himself mentions addictions to pornography and masturbation at that time. He set about plotting, planning, for an opportunity to be alone with her. When the Goretti’s and Serenelli’s worked in the fields, Maria watched and cared for her baby sister, and worked on sewing the items her mother placed in the mending basket. Alessandro slipped away from the field and went to the house under the pretext of wanting a glass of water. Maria had been sitting just outside the door, on the step, within earshot of her sister. She went into the house to get the water and Alessandro followed her, he then cornered her and demanded that she submit to him. She refused and told him that it was a sin. He grappled with her, tore her dress, and repeated his demands. She pushed him away and said she would not, it was a sin. She would not help him by cooperating in this sin because he would go to hell. She would not offend God by consenting to such impurity.
Alessandro says that he became enraged, he pushed her down and ripped the bodice of her dress, and yanked her skirt up. She tried to push him off, and kept saying , “No Alessandro, it is a sin, you will go to hell”. It was at that point that he produced the knife and stabbed her. She isn’t a model of purity because she fought off a potential rape. She’s a model because she would not consent to his demands for sexual intercourse. The rape attempt only came after she warded off his sexual advances. And he wasn’t successful at that because she chose to be an unwilling victim. He didn’t go to the house with the intent of raping Maria, he wanted her cooperation in the sin; which she would not do even when he produced the knife and indicated to her the ultimatum, submit or die. The rape attempt was a last ditch attempt to get what he originally wanted, but when he realized that she would fight his attempts and he wouldn’t succeeed, then he stabbed her.
Serenelli also felt trapped; Maria’s and his voices awakened the baby, and he was afraid that the cries would be heard from the fields. So he stabbed her several times then quickly exited the house. Sure enough, Maria’s mother heard the baby crying, and returned to the house to find her daughter lying in a pool of blood with her clothes disheveled. Maria, trying to preserve her modesty by pulling the torn fabric over her bosom, said to Assunta, “It was Alessandro, Mama. He wanted to commit a grave sin, and I said “No””. On the way to the hospital, Maria not only forgave Alessandro Serenelli, she said she would spend her eternity praying for his conversion. Her sanctity is a result of her refusal to submit to fornication, her forgiveness of her attacker, and her desire that he would convert, repent, and spend eternity in Heaven. She never, at any time, held any ill will towards the young man. It tales extraordinary holiness to forgive the person who repeatedly pressured you to yield to his impure desires, then stabbed you because of your refusal to cooperate in sin with him.
A lot of books and movies tend to water down the details, or exaggerate to the point of making the saint seem unapproachable. cathmomonline, I hope reading this, much of which came from first hand accounts by Allessandro Serenelli and Assunta Goretti; will help you to understand where Maria’s purity plays a role in her sanctity. As well as her forgiveness, and desire for repentance, of her attacker. Maria did physically fight him, but a 12 yo girl is physically no match for an 18 yo teenage boy who was exceptionally strong due to laboring in the fields. She not only wouldn’t cooperate in sin with him, she wouldn’t even be an unwilling partner and allow him to endanger his soul without her help. She was as much concerned with his salvation as she was her own. His conversion ultimately took place following a dream he had of her.
