St. Patrick and the King

In the Country of Neyll, a King Echu allowed St. Patrick to receive his beloved daughter Cynnia as a nun, though he bewailed the fact that his royal line would thereby end without issue. The King exacted a promise from Patrick not to insist that he be baptized, yet to promise him the heavenly kingdom. Patrick agreed, and left the matter in the hands of God.
Sometime later King Echu lay dying. He sent a messenger to St. Patrick to tell him that he desired Baptism and the heavenly kingdom. To those around him the King gave an order that he be not buried until Patrick came. Patrick, then in the monastery of Saballum, two days' journey away, knew of the situation through the Holy Spirit before the messenger even arrived. He left to go to the King, but arrived to find Echu dead. St. Patrick revived the King, instructed him, and baptized him. He asked Echu to relate what he had seen of the joys of the just and the pains of the wicked, so that his account could be used for the proving of Patrick's preaching. Echu told of many other-world wonders and how, in the heavenly country, he had seen the place Patrick had promised him. But the King could not enter in because he was unbaptized. ...Then having received the Eucharist, he fell asleep in the Lord.

St. Martin and the Catechumen

Martin restores a Catechumen to Life.

"...At this time a certain catechumen joined him, being desirous of becoming instructed in the doctrines: and habits of the most holy man. But, after the lapse only of a few days, the catechumen, seized with a languor, began to suffer from a violent fever. It so happened that Martin had then left home, and having remained away three days, he found on his return that life had departed from the catechumen; and so suddenly had death occurred, that he had left this world without receiving baptism. The body being laid out in public was being honored by the last sad offices on the part of the mourning brethren, when Martin hurries up to them with tears and lamentations. But then laying hold; as it were, of the Holy Spirit, with the whole powers of his mind, he orders the others to quit the cell in which the body was lying; and bolting the door, he stretches himself at full length on the dead limbs of the departed brother. Having given himself for some time to earnest prayer, and perceiving by means of the Spirit of God that power was present, he then rose up for a little, and gazing on the countenance of the deceased, he waited without misgiving for the result of his prayer and of the mercy of the Lord. And scarcely had the space of two hours elapsed, when he saw the dead man begin to move a little in all his members, and to tremble with his eyes opened for the practice of sight. Then indeed, turning to the Lord with a loud voice and giving thanks, he filled the cell with his ejaculations. Hearing the noise, those who had been standing at the door immediately rush inside. And truly a marvelous spectacle met them, for they beheld the man alive whom they had formerly left dead. Thus being restored to life, and having immediately obtained baptism, he lived for many years afterwards; and he was the first who offered himself to us both as a subject that had experienced the virtues of Martin, and as a witness to their existence. The same man was wont to relate that, when he left the body, he was brought before the tribunal of the Judge, and being assigned to gloomy regions and vulgar crowds, he received a severe sentence. Then, however, he added, it was suggested by two angels of the Judge that he was the man for whom Martin was praying ; and that, on this account, he was ordered to be led back by the same angels, and given up to Martin, and restored to his former life. From this time forward, the name of the sainted man became illustrious, so that, as being reckoned holy by all, he was also deemed powerful and truly apostolical."
