Columba is trained by Irish monks. However, his youthful Christianity is skin-deep while his passions are strong. He is partly responsible for the battle of Cul-drebene in which many men lose their lives. Repentant, he sails to Britain as “a pilgrim for Christ” and founds the monastery of Iona, from which Christianity spreads across North Britain. He himself travels and preaches, establishing several churches and monasteries.
Traveling in Scotland, Columba has to cross the Loch Ness. On its banks, he sees some of the Picts burying a man who had been bitten by a water monster while swimming. The body had been pulled from the loch with the aid of a hook by rescuers who had come to his assistance in a boat.
Despite the danger, Columba orders one of his followers to swim across the loch and bring back a boat that is moored on the other side. This man’s name was Lugne Mocumin. Without hesitation, Lugne strips for the swim and plunges in.
The monster, robbed of its earlier feast, surfaces and darts at Lugne with a roar, its jaws open. Everyone on the bank is stupefied with terror, everyone except Columba, that is. A firm believer in the authority of the crucified Christ, he raises his hand, making the sign of the cross. Invoking the name of God, he commands the beast, saying, “You will go no further, and won’t touch the man; go back at once.”
At the voice of the saint, the monster flees as if terrified, “more quickly than if it had been pulled back with ropes,” says Adomnán. The heathen are amazed. Everyone who witnesses the sight gives glory to the God of the Christians.
The authenticity of this event remains in doubt. To begin with, Adomnán’s account is written over a hundred years after the alleged events. Furthermore, different versions of the story disagree with one another. One has Columba raising the monster’s first victim from the dead by laying his staff across his chest.
This is only one of many extraordinary events in Adomnán’s account. According to him, Columba drips with prophecies and predictions that come true. He makes water into wine like Jesus, draws water from a rock like Moses, calms a storm at sea, provides a miraculous draught of fishes, multiplies a herd of cattle, drives a demon out of a milk pail, and cures the sick. A book owned by Columba could not be destroyed by water. Through his prayers he kills a wild boar, stops serpents from harming the inhabitants of a certain island. Angels and manifestations of divine light attend him throughout his life. Adomnán’s account has so many incredible tales that it is unbelievable.
