The following is how one becomes a saint according to the "Church" (Catholic Church)
This is an excerpt from http://www.catholic.org/saints/faq.php.
"How does the Church choose saints?1 Corinthians 1:2
Unto the church of God which is at Corinth, to them that are sanctified in Christ Jesus, called to be saints, with all that in every place call upon the name of Jesus Christ our Lord, both theirs and ours:
How does God call people today?
God calls people today by the gospel.
1 Corinthians Chapter 15:1-4
Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have
received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached
unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also
received, how that Christ died for our sins according to the scriptures; And that he was buried,
and that he rose again the third day according to the scriptures:
Once you have trusted in that gospel, you become a saint of the Most High God. There are no need
of confirmed miracles, no evidence of clean living, or anything else. This is a spiritual transaction
that takes place. The Spirit of God is there and that is all of the evidence God needs. When He
looks at you now, all He sees is you have been placed into Christ. That is what it takes to be saint.
Grace and Peace,
Complete in Him
