Lull equipped lay merchants to argue the Trinity against Muslims and Jews alike

Evidence

Merchants, he said, who often did business in Islamic countries, were asked about the Christian religion by Muslims anxious for discussions; out of ignorance they often did not know how to answer and were ‘in doubt about the religion of Muhammad’. Now Lull would dispel this difficulty. He would show them how to demonstrate that the Christian religion is better, greater and truer than any other, by a method, in fact, that was equally efficacious against the Jews. Of course, it was solely concerned with the Trinity. — Norman Daniel, Islam and the West, 990
