 Leo XIII advised Rua to hold off on the order's expansion until he could consolidate the foundation that Bosco had worked to build.Rua was nicknamed as "The Living Rule" due to his austereness and his strict adherence to the rule; he was also known for his tender approach and thoughtfulness to people.He made frequent visits to Salesian houses in Europe and in the Middle East and made constant referrals to the example of the late Bosco.
