The show features many characters that reflect Biblical characters or religious values.
Jane as The Virgin Mary
Jane Gloriana Villanueva is the main character on the show Jane The Virgin. Her story parallels that of The Virgin Mary from Christianity. Jane decides at a young age that she wants to stay a virgin until she is wed and plans to marry her longtime boyfriend Michael, but becomes pregnant (when her doctor accidentally artificially inseminates her). Jane is seen as a wholesome and pure motherly figure in the show, similarly to the Virgin Mary. She has a very deep connection to God and while she has questioned her own faith at times, she has always come back to being a devout Catholic (season 1, episode 18).
Michael as Joseph
Michael, Jane's boyfriend, can be seen as a Joseph-like figure. When Michael first learns about Jane's pregnancy, he is not pleased about it and considers leaving Jane, similarly to Joseph with Mary. He does end up marrying Jane though (season 2, episode 2) and becomes a father figure to her son, Mateo. Saint Joseph is the patron saint of happy deaths and Michael's death, as sudden and tragic as it is, is a happy one. The narrator explains that at the moment of his death Michael's heart was happy and full of love for Jane (season 3, episode 10).
Mateo as Jesus
It is hard to tell if Matteo will live up to Jesus, as he is only a small child on the show. However, he his life has resembled Jesus' so far. Matteo was born of Jane, a virgin (season 1, episode 22), which is very similar to Jesus whose mother was also a virgin. Also, shortly after his birth, people come to the hospital in attempts to kidnap and kill Mateo (season 1, episode 22). This resembles the Massacre of Innocents in the Bible when Jesus' life is at stake as an infant.
Alba as Good or The Voice of Reason
Alba is Jane's religious grandmother and while she does not represent a character or figure from the Bible, she represents Catholic values. Alba is often the voice of reason and is Jane's go to person when she is looking for advice. Alba's advise is often religious or influenced by her religious beliefs. For example, Alba is adamant about ensuring that Mateo attends church regularly when Jane is feeling angry at God for killing Michael and unsure about whether her son should be religious (season 3, episode 7). Alba is the one who first told Jane that her virginity was linked to her relationship with God and that she should wait to have sex until marriage. Despite Alba always stepping in with the WWJD advice, some of her views stem from mistakes she had in her past and times she turned to God, like having sex before marriage and encouraging her daughter to have an abortion when she got pregnant as a teenager.
Petra as Evil
Petra, like Alba, is not a representation of a Biblical figure. However, Petra's character also differs greatly from Alba's. While Alba is often seen as the voice of reason and a godly woman, Petra is a corrupt business woman who thinks of no one but herself (until she has children). Petra is very greedy and artificially inseminates herself when Rafael is giving all his attention to the mother of his child, Jane (season 2, episode 3). This is after her and Rafael divorced because of her adulterous habits. Many of the behaviours that Petra demonstrates expose her as a greedy and ruthless woman, which do not correspond with the show's Christian values. However, Petra is praised on the show as an expert business woman.
Rafael as Redemption
In the beginning of the show, Rafael is married to Petra and is just as evil as her one could say. He comes from a very wealthy family and is about to take over the family business. He is described as a former playboy. However, all this changes when he discovers that Jane is carrying his child (it was his specimen when she was artificially inseminated). Rafael begins to turn to Jane to become a better person. This can be seen as someone changed by Jesus (Mateo) and turning to holy figures like Mary (Jane) for help. Jane even encourages Rafael to attend church with her (season 3, episode 7).
