Not all the questions of the day were settled as easily. One of the most important ones was who should succeed Mary on the throne. If she married and had children, they would be her heirs, but if not, the Princess Elizabeth would probably follow her as ruler of England. Now Mary was a strong and sincere Catholic, and her dearest wish was to lead England back to the old faith and have the Pope acknowledged as the head of the English church. She hoped to be able to bring this to pass, but she was not well, she had little reason to look for a long life, and when Elizabeth became queen, all Mary’s work would be undone, the land would be again Protestant. Elizabeth was to Mary still the little sister whom she had so often led by the hand. Would it not be possible to persuade her to become a Catholic? Elizabeth had loved Edward, would she not go with Mary to hear a mass for the repose of his soul? Elizabeth refused. Again Mary asked, and again Elizabeth said no.

“She would not dare be so bold if stronger than herself were not behind her,” declared Mary’s councilors. “There is danger to life and throne in this audacity.” Others too were to be feared, those Protestants who did not believe in the right of Elizabeth to the crown. They were not sorry to see disagreement between the two sisters, for if the younger should be shut out from the succession, Lady Jane, prisoner in the Tower as she was, would be accepted as Mary’s heir. Evidently Elizabeth must be induced to become a Catholic if it was possible. Mary begged and then she threatened. She had sermons preached before Elizabeth, and she sent the royal councilors to talk with her, but in vain. At last the princess was made to understand that she must yield or withdraw from court. More than this, it was said to her, “There are suspicions that you are bold in resisting the queen because you have support from without.”

Elizabeth was alarmed, and she sent a message to the queen:—

“I pray you, let us meet, there is much that I would say.” Soon the meeting came to pass. Mary entered the room attended by only one lady, who followed her at a greater distance than was customary. Elizabeth threw herself at Mary’s feet and said with many tears:—

“Most gracious queen and sister, I have ever looked up to you with love and respect, and since I have had the use of my reason, I have been interested in everything that concerns your greatness and glory. It grieves me to the heart to feel that for some reason unknown to myself I am no longer as dear to your Majesty as I have believed myself to be.”

“My well-beloved sister,” answered the queen, “gladly would I show to you all affection if I were but sure that your heart was turned toward me and toward that which is not only my dearest wish but is for the salvation of your own soul.”

“I have but followed the belief in which I was brought up,” said Elizabeth. “Such books as my father approved have been my reading. I will study others if you will, and it may be that my mind will be opened to perceive truth in doctrines wherein I had not thought it to lie.”

“It will be a pleasure to my chaplain to choose for you those that are of such quality as to lead a truly inquiring heart into the way of right.”

“Yet another kindness do I beg of you, my queen and sister,” said Elizabeth. “I have listened to those whom I was told to hear. Will your Grace send to me some well-taught preacher to instruct me in the way wherein you would have me to walk? Never have I heard any learned doctor discourse in such wise as to show me where lay my error.” Mary agreed, and a few days later the two sisters attended mass together. Elizabeth even wrote to the German emperor that she intended to have a Catholic chapel opened in her own house, and asked his permission to purchase in Flanders a cross, chalice, and such ornaments as would be needed.

No one had much confidence in her sudden change of creed. Those Protestants who were discontented went on with their plots to make her queen, convinced none the less that once on the throne, she would restore the Protestant form of worship. The German emperor, who was Mary’s chief adviser, urged that to insure the queen’s safety Elizabeth ought to be imprisoned, or at any rate, so strictly guarded that she could do no harm. There was reason for his fears. Mary, Queen of Scots, would soon become the daughter-in-law of the French king, and while he was pretending to be a true friend to Elizabeth, he was in reality doing all in his power to make trouble between her and Mary. If Elizabeth could be led into some plot that would anger Mary and so could be shut out from the succession, his daughter-in-law might easily become queen of England as well as of Scotland. Vague rumors of discontent and plots came to the ears of Mary, and for some time she refused Elizabeth’s request to be allowed to go to her own house.
