When did Saint Blaise become a saint?

Answer 1

Saint Blaise became a saint the instant he died and entered heaven. He was never canonized and is considered a 'precongregational saint.' He was declared a saint by the early Church based on his martyrdom.

Answer 2

St. Blaise is a "pre-congregational" saint. It was not until about the 12th century that a formal canonization process was instituted. Before that time, people were proclaimed a saint by popular acclaim.

St. Blaise was not canonized. He was proclaimed a saint by early Christians because of his martyrdom. The modern canonization process did not come into existence until the 12th century. In the primitive Church, martyrs were immediately recognized as witnessing to the perfection of Christian life on earth, having shown the ultimate proof of their love for Christ by the offering of their lives. By the sacrifice of their lives for Christ, they attained Heaven in eternal glory and were indissolubly united to the Lord, the Head of the Mystical Church Body.
