When was Saint Lucy canonized a saint?

Saint Lucy was not canonized. She was proclaimed a saint by early

Christians because of her martyrdom. The 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 Body.
