According to the New Testament, the word "saint", which means "called out or the called out ones", refers to believers in general; it is not used for specific persons. Paul, among others, sometimes addressed his letters, "To the saints at..." So, to become a "saint", one simply needs to become a believer in and follower of Jesus Christ.

Sainthood is defined as the process by which holy men and women are officially recognized for their heroic activity. To get into that category, a person’s life is thoroughly investigated by Church authorities after death and many miracles are expected through the intercession or influence of that person’s prayers. The Mass book and Church calendar designate them by categories: apostles, martyrs, pastors, virgins and founders of religious orders. A brief explanation of this process by Father Daniel Maher can be found here: http://www.legionsaints.org/canonize.html

Many of the world's religions bestow special status on people who demonstrate a life of almost perfect virtue. Religions differ on the title assigned to these people. The Catholic church calls them saints. The process by which someone becomes a saint is called canonization. The Catholic church has canonized around 3,000 people -- the exact number is unknown because not all saints were officially canonized. According to the Catholic church, the pope does not make someone a saint -- the designation of sainthood only recognizes what God has already done. For centuries, saints were chosen through public opinion. In the 10th century, Pope John XV developed an official canonization process. Canonization has been revised in the last 1,000 years, most recently by Pope John Paul II in 1983. Pope John Paul II, who has canonized more than 280 people since 1978, made several procedural changes to the canonization process, including the elimination of the "devil's advocate" from the review process. The devil's advocate was the person designated to attack the evidence offered in favor of canonization. The process of becoming a Catholic saint is very lengthy, often taking decades or centuries to complete. Here are the steps that must be followed: 1) A local bishop investigates the candidate's life and writings for evidence of heroic virtue. The information uncovered by the bishop is sent to the Vatican. 2) A panel of theologians and the cardinals of the Congregation for Cause of Saints evaluate the candidate's life. If the panel approves, the pope proclaims that the candidate is venerable, which means that the person is a role model of Catholic virtues. 3) The next step toward sainthood is beatification. Beatification allows a person to be honored by a particular group or region. In order to beatify a candidate, it must be shown that the person is responsible for a posthumous miracle. Martyrs, those who died for their religious cause, can be beatified without evidence of a miracle. 4) In order for the candidate to be considered a saint, there must be proof of a second posthumous miracle. If there is, the person is canonized. These alleged miracles must be submitted to the Vatican for verification. Once a person is a saint, he or she is recommended to the entire Catholic church for veneration. AND in response to the protestant definition of "saint", your answer makes sense from a protestant view, but the Catholic religion recognizes saints in a very different way.

To become a saint as the word of god has prescribed, one must believe in Christ, if we a beloved of christ he will make intercession for us. (romans 8:27) God loves us all we are all valued to him as childern with divine potentail, even heirs of glory with him (romans 8:16-18) so don't get to worried about being a saint, we all can and must be inorder to live with christ forever. Make no mistake though true saints do much more than simply profess christ with there lips they endure to the end in faith (matt. 10:22) So keep the faith and find the truth through pray (james 1:5) and honest seeking and knocking (matt. 7:7-8) ame yall
