“Among those who blamed the extraordinary life of Catharine, the most remarkable was Father Lazarini, of the Order of Friar Minors, who was then professing Philosophy with eclat, in his convent of Sienna. Not content with openly attacking the reputation of the Blessed, he resolved to come and see her, so as to find in her words and actions, materials for condemning her further: on the eve of [the Feast of] St, Catharine [of Alexandria] Virgin and Martyr he repaired to her house at the hour of Vespers. He had requested me to accompany him and I [Friar Bartholomew of Sienna] had consented to it, because I believed that he would repent of his conduct towards her. We entered her pious cell; Lazarini seated himself on a chest, and Catharine on the floor at his feet; I remained standing. After a few moments of silence, Friar Lazarini began to speak : ‘I have heard’ said he ‘many speaking of your sanctity, and of the understanding God has given you of the Holy Scriptures, and I have been eager to visit you hoping to hear something edifying and consoling to my soul.’ — Catharine replied: ‘And I, rejoice at your arrival, because I think that the Lord sent you to allow me an opportunity of profiting by that learning, with which you daily instruct your numerous disciples. I hoped that charity would induce you to comfort my poor soul, and I entreat you to do so through love of Our Lord.’ The conversation continued some time in this tone, and as the night was approaching Friar Lazarini finished by saying: ‘I see that it is late, and that I must retire, but I will return at a more suitable hour’. He arose to depart; Catharine knelt, crossed her arms, and asked his blessing When she had received it, she commended herself to his prayers, and Friar Lazarini, more through politeness than from devotion, asked her also to pray for him which she cheerfully promised to do. He went away, thinking that Catharine might be a good person, but that she was far from meriting her great reputation.
The night following, on rising to study the lesson that he was to explain to his pupils the next day, Friar Lazarini began to shed tears involuntarily. The more he wiped them, the more copiously they flowed, and he could not discover the cause In the morning, they came to call him at the hour of Class; but it was impossible for him to speak to his pupils: he wept without intermission. Returning to his cell, he continued weeping, and was indignant towards himself. ‘What ails me,’ said he; ‘what do I want: is my mother dead suddenly, or has my brother fallen on the battle-field; what can this mean?’ The entire day passed in this state, and when evening came on, he slept a few moments, being overcome with fatigue and wearisomeness; but he soon awoke, and his tears began to flow afresh, without his being able to restrain them. He therefore reflected whether he might not have committed some grave fault, and invoked the divine Mercy to recall it to him: whilst he was examining his conscience, he heard an interior voice that exclaimed to him: ‘Do you forget so quickly that yesterday, you judged my faithful servant Catharine in a spirit of pride, and requested her to pray for you through politeness?’
As soon as Friar Lazarini had received this advertisement and discerned his fault, his tears subsided and his heart became inflamed with a desire of again conversing with Catharine. At the first glimmering of day, he hastened to knock at the door of her cell. The Blessed, who was aware of what her Spouse had done, opened the door to Friar Lazarini, who prostrated himself at her feet, Catharine also prostrated, and implored him to rise, after which they had a lengthy interview, and the Religious conjured her to condescend to direct him in the way of salvation. Catharine, overcome by his instances answered him: ‘The way of salvation for you is, to despise the vanities of the world and its smiles, to become humble, poor, and destitute in imitation of Jesus Christ and your holy Father, Saint Francis.’ At these words the Religious saw that Catharine read his soul; he shed tears profusely and promised to do whatever she might command him. He accomplished his promise, distributed his money, and useless furniture, and even his books. He merely reserved a few notes, which were necessary aids to him when preaching, and became truly poor, and a veritable follower of our Blessed Redeemer.”
