He heard but little of "Mormonism" after that until he removed to Birkenhead, in 1846. While going from there to Liverpool in company with some of his relatives and friends, he met a "Mormon" Elder, who invited him to attend one of their meetings to be held in the last named place. He persuaded his companions to accompany him, and they all attended the meeting. While listening to the Elders bear their testimony to the great latter-day work, he felt convinced that they spoke the truth, and believed them with all his heart.
At the close of the meeting, he asked one of his friends, a Campbellite preacher, what he thought of the "Mormons" and their doctrines. The preacher replied that their doctrines were a "damnable heresy."
"Well," said Mr. Parry, "one of the sayings of Paul has been fulfilled with you and me to-day."
"What is that?" asked the preacher.
"When he said the gospel would be unto one 'the savor of death unto death: and to the other the savor of life unto life.' It has been life unto life to me, and I shall be a Latter-day Saint," was the response.
He attended another meeting in the evening of the same day, and at the close he and his father handed in their names for baptism.
Shortly after he was baptized Brother Parry was ordained an Elder and was appointed to preside over the Birkenhead branch of the Church. While praying subsequently for a testimony of the truth, a voice spoke to him and said: "The gift of healing shall follow thee to a great extent."
This was literally fulfilled.
After joining the Church Elder Parry was often troubled in his sleep by evil spirits. Upon one occasion he inquired of the president of the Liverpool branch why it was that he was thus annoyed. The Elder replied that some persons were troubled more than others, and told him to use the following words in his prayers before retiring to rest: "O God, the Eternal Father, I ask Thee in the name of Thy Son, Jesus Christ, to give Thine angels charge concerning me this night, and allow not the powers of darkness to molest my spirit nor body."
He did this, and was troubled with evil spirits no more, until one night, feeling very sleepy, he uttered a hasty, formal prayer and went to bed. During the night he was almost overcome by the power of evil spirits, which were visible. Unable to utter a word, he prayed fervently in his mind to the Lord to release him. In an instant the heavens appeared to him to open, and he saw an angel descend towards him. The personage took hold of him and raised him up a little, and immediately the powers of darkness disappeared.
