I am curious to see how the author continues to portray Luis Frois, and am pleasantly surprised, so far.
I hope, though, seeing how well researched the author is in other areas, even though missionaries, in principle, have the secondary goal of promoting human health, life, and dignity of all individuals, that they don't have Frois "venerate" her on the grounds of sharing such a goal and knowledge of scripture, or even perceived miracles, for that matter.
Since he is clergyman, a member of the ecclesiastic structure, he should know how prudent and careful the Church is about who is declared a saint. In order for someone's cause to be opened to canonization, the must believe there is sufficient proof that the person was an ardent servant of Christ, as well as filled with the supernatural Life of Christ, something obtained through the sacraments, principally Baptism, or otherwise martyrdom. In the tradition of Paul's words: "it is no longer I who live, but Christ who lives in me".
It is only when the College of Cardinals exhausts all credible documentation of the persons life, with additional requirements of evidence of that person's 'God-centered-sanctity', particularly up to the moment of their death, that they may declare that the 'saint-in-question' is, beyond a reasonable doubt, in union with God in heaven, and therefore a universal saint.
For the Fellow Reader's information.
