It presents a primary use to the instigation of religion, since in the Catholic Church a person who is already deceased and who has notable virtues that were duly highlighted and certified by the Pope is thus called. For such a question it is that the blessed can be venerated of a cult.
Now, it is worth mentioning that not all individuals are plausible to be declared blessed, but that such a situation will only be possible in those cases of individuals who when they died already had popularity in matters of holiness, and even the same, was widespread throughout the world. Meanwhile, beatification can materialize for two reasons, if the faithful had virtues and lived heroically, or if the individual in question suffered martyrdom as a result of his fervent religious faith.
It is important to note that many people tend to confuse the term blessed and holy, although they are quite similar, they are different titles and with different attributions granted by the Catholic Church to individuals with a dignified and virtuous life of veneration.
When we refer to the blessed, we are talking about the model of life of a person according to the precepts of Christianity who has gone through the beatification process. For this process to take place, there must have been at least one miracle attributed to the candidate, verified by a committee of experts, the miracle is not a requirement if the person was a martyr of the church. In the process of beatification, it is the bishop of the diocese where the candidate died who asks him to be blessed. The Blessed One is venerated by the people, but only in places close to the town where he lived, region or country. To be revered in other dioceses or congregations, a permission or "pardon" may be requested from the Vatican to do so.
In the case of the saint, it could be defined as the title next to the blessed, a degree that gives to the church, it is given when the blessed goes through the canonization process if the condition of a miracle is fulfilled through the intercession of the candidate, who it must occur within five years after your death. The pope has the power to circumvent these requirements for some special reason. By being named a saint, the Catholic Church as a whole gives him a day for his universal veneration and the churches can dedicate themselves to his worship, he is also included in the canon, which is the official list of saints of the Catholic Church.
In conclusion, blessed and holy are titles conferred by the church to men, examples of Christian life, who have gone through a series of requirements for their appointment, the saint has a degree more than the blessed. The difference lies primarily in the extent of their veneration within the Catholic Church. The Blessed One is venerated locally under the permission of the Pope, and the saint is venerated throughout the church by decree of the Supreme Pontiff.
