He knew it would not be easy
One of the obstacles was that there were no seminaries near where he lived. The nearest seminary that would take him was over a thousand miles away.
He also knew his decision would not be popular, so he kept his studies secret.
Finally, he knew that it would be dangerous, but it was something he had to do, it was what he was called to do.
Andrew's wish would be fulfilled. He was ordained a priest of Jesus Christ.
Andrew's fear would be realized quickly. The year after his return home, in 1846, Andrew Kim Taegon and his father were executed by the Korean government, together with Paul Chong Hasang, a lay apostle, and many others.
More martyrdoms would follow, but Church in Korea would survive and eventually thrive. In less than a century and a half, in 1984, the great Pope John Paul II would visit Seoul and there canonize Andrew and 102 other Korean martyrs for Christ.
Their memory is celebrated on this day.
