Any saint by definition has achieved sainthood, except that some 'saints' are angels (St. Michael) and some saints were not canonized (St. Cecilia).
There are undoubtedly saints alive today. However, to be officially recognized as a saint by the Church a person must first die and be officially canonized as a saint.
I am not sure which of the many Teresas you are referring to but there were many, many female saints long before any of them were canonized.
No, this is actually impossible. By definition, a "saint" is essentially any soul that currently resides in Heaven, including angels as well as humans. This means that even if you were not canonized but made it to Heaven, you are a saint (with a lower-case 's'). In order to become a Saint, the Pope must say a cannonization mass in your honor after you pass away and your soul has been determined to be definitely in heaven. This cannonization process often times takes years if not centuries.
There are a number of saints named Francis. Please be specific. However, ALL canonized saints are given a feast day when tye are beatified. On any given day of the year 15-20 or more individuals are recognized.
There are saints named Ann and Anne but no Leann.
Before the 12th century there was no official system for canonization. Saints were declared by popular acclamation, usually with the approval of a bishop. In the 12th century the power to declare saints was removed from local control and placed with the pope. Today the office in Rome that investigates candidates for sainthood is called the Sacred Congregation for the Causes of Saints. Saints declared before the 12th century are thus called pre-congregational saints. The Congregation investigates possible saints and makes recommendations to the pope.
There are at least three saints named Justina and all were martyrs during the early years of the Church. No birthdate is known for any of these saints.
There is no saint named Garrett in the Bible. Also, I can find no canonized saint in the Catholic Church named Garrett.
I can find no reference to any saint named Lola.
That depends upon your view of who is a saint. a very religious person can be a saint, or even a person who does only good for others and has not done a bad thing in his/her whole life. However, to be a recognized saint (canonized) the person must be dead.
I find no reference to any canonized saint named Cassie.
