His first care was to look into both the ancient and modern history of the church; to ascertain its beginning and progress; to consider the causes of all those controversies which in the meantime had sprung up, and diligently to weigh their effects, solidity, infirmities, &c.

Before he had attained his thirtieth year, he had studied the Greek and Latin fathers, and other learned authors, the transactions of the councils, and decrees of the consistories, and had acquired a very competent skill in the Hebrew language. In these occupations, he frequently spent a considerable part, or even the whole of the night, and in order to unbend his mind after such incessant study, he would resort to a grove near the college, a place much frequented by the students in the evening, on account of its sequestered gloominess. In these solitary walks, he has been heard to ejaculate heavy sobs and sighs, and with tears to pour forth his prayers to God. These nightly retirements, in the sequel, gave rise to the first suspicion of his alienation from the church of Rome. Being pressed for an explanation of this alteration in his conduct, he scorned to call in fiction to his excuse; he stated his opinions; and was, by the sentence of the college convicted, condemned as a heretic, and expelled.

His friends, upon the report of this circumstance, were highly offended, and especially his father-in-law, who was now grown altogether implacable, either through a real hatred conceived against him for this cause, or pretending himself aggrieved, that he might now, with more show of justice, or at least with more security, withhold from Mr. Fox his paternal estate; for he knew it could not be safe for one publicly hated, and in danger of the law, to seek a remedy for his injustice.

When he was thus forsaken by his own friends, a refuge offered itself in the house of Sir Thomas Lucy, of Warwickshire, by whom he was sent for to instruct his children. In this house he afterwards married. But the fear of the popish inquisitors hastened his departure thence; as they were not contented to pursue public offences, but began also to dive into the secrets of private families. He now began to consider what was best to be done to free himself from further inconvenience, and resolved either to go to his wife's father or to his father in-law.

His wife's father was a citizen of Coventry, whose heart was not alienated from him, and he was more likely to be well entreated, for his daughter's sake. He resolved first to go to him; and, in the meanwhile, by letters, to try whether his father-in-law would receive him or not. This he accordingly did, and he received for answer, "that it seemed to him a hard condition to take one into his house whom he knew to be guilty and condemned for a capital offence; neither was he ignorant what hazard he should undergo in so doing; he would, however, show himself a kinsman, and neglect his own danger." If he would alter his mind, he might come, on condition to stay as long as he himself desired; but if he could not be persuaded to that, he must content himself with a shorter stay, and not bring him and his mother into danger.

No condition was to be refused; besides, he was secretly advised by his mother to come, and not to fear his father-in-law's severity; "for that, perchance, it was needful to write as he did, but when occasion should be offered, he would make recompense for his words with his actions." In fact he was better received by both of them than he had hoped for.

By these means he kept himself concealed for some time, and afterwards made a journey to London, in the latter part of the reign of Henry, VIII. Here, being unknown, he was in much distress, and was even reduced to the danger of being starved to death, had not Providence interfered in his favour in the following manner:

One day as Mr. Fox was sitting in St. Paul's church, exhausted with long fasting, a stranger took a seat by his side, and courteously saluted him, thrust a sum of money into his hand, and bade him cheer up his spirits; at the same time informing him, that in a few days new prospects would present themselves for his future subsistence. Who this stranger was, he could never learn, but at the end of three days he received an invitation from the dutchess of Richmond to undertake the tuition of the children of the earl of Surry who, together with his father, the duke of Norfolk, was imprisoned in the Tower, by the jealousy and ingratitude of the king. The children thus confided to his care were, Thomas, who succeeded to the dukedom; Henry, afterwards earl of Northampton; and Jane who became countess to Westmoreland. In the performance of his duties, he fully satisfied the expectations of the dutchess, their aunt.

These halcyon days continued during the latter part of the reign of Henry VIII. and the five years of the reign of Edward VI. till Mary came to the crown, who, soon after her accession, gave all power into the hands of the papists.

At this time Mr. Fox, who was still under the protection of his noble pupil, the duke, began to excite the envy and hatred of many, particularly Dr. Gardiner, then bishop of Winchester, who in the sequel became his most violent enemy.
