When the tribe was successful in battle, then certain dues were paid to the saint for his assistance.
In the lives of some of the early Celtic saints we are told strange stories of their self-mortification, their rigorous fasts. This was due to a very curious cause.
According to the Celtic law of distress, the appellant took the matter into his own hands. There was no executive administration of law. Everyone who was aggrieved had to exact the penalty as best he might. If he were too weak to recover the penalty by force, then the legal proceeding for him was to fast against the debtor or aggressor. He sat down at his door and starved himself. The person fasted against almost always gave way, as the fact of the institution of the fast doubled the fine, and as he did not venture to allow the creditor to proceed to the last extremities lest he should entail on himself a blood feud.
When S. Patrick wanted to carry a point with King Lear (Laogaire) he adopted this method and succeeded, and the king gave way.
There is a very odd story--of course mere legend--of S. Germanus when he came to Britain to oppose the Pelagian heresy. He found one particular city mightily opposed to the orthodox doctrine, and as he could not convince the citizens by reasoning with them, he and his attendant clerks sat down at the gates and starved themselves to force the citizens into adopting the true faith.
The same law of distress is found in the code of Menu, and the British Government has had to forbid the dharma--i.e. the legal fasting against a creditor--from being put in practice in India.
Now, very naturally, and by an easy transition, the early Celtic saints carried their legal ideas into their religion, and just as when S. Patrick, wanting something from King Lear, fasted against him till he obtained it, so did the followers of Patrick, when they desired something of God for themselves or for others, proceed against Him by the legal method of levying a distress.
This is frankly admitted in an odd story in the Book of Lismore. Three clerks agreed together that they would each recite a certain number of psalms daily, and that should one die the other two would share his psalms between them. All went smoothly enough for a while. Then one died, whereupon the survivors divided his portion of the Psalter between them. But soon after a second died, whereat the third found himself saddled with the sets of psalms that appertained to both the others. He was very angry. He thought the Almighty had dealt unfairly by him in letting the other two off so lightly and overburdening him, and in a fit of spleen and resentment he fasted against Him.
But this view of asceticism was held only at the outset, and rapidly sounder ideas gained the mastery, and we find self-denial in the saints assume quite another complexion.
An instance in point is in the life of S. Columba. One day he saw a poor widow gathering stinging-nettles, and he asked her why she did it. "For the pot," said she; "I have no other food."
