Sir Moses Salvadore

Sir Salvadore came to faith in 1852. He was a wealthy and influential Jew, member of an esteemed and powerful sephardic family of Portuguese descent. One of his ancestors built Salvador HOuse, near the Royal Exchange in London. The senior branch of the family settled in Amsterdam, when the Jews were expelled from Spain, and brought with it immense wealth. Sir MOses Salvador was led, by the providence of God, through most extraordinary ways to Christ. These terminated in the conviction and public profession that Jesus is the Son of God, the true Messiah.
This conviction did not come lightly or suddenly. Gidney tells us that two years before his profession of faith and baptism, he had said to Rev. Pauli, the London Society missionary, “The time will come, when you will hear that I am working with you for the spiritual deliverance of our brethren.”
That time came two years later, in 1852. Every Thursday evening he taught a public course on Christianity that was attended by some of the most influential and respectable of the Amsterdam Jewish community.
Gidney comments that “This event caused no common agitation, and at the same time no small perplexity to the rabbis, especially of the Portuguese synagogue.”
