From that moment he devoted himself to the exclusion of James.
In 1676 the Duke of York made it known that he had become a Catholic. This was so gratuitous that people took it to mean that he was strong in the support which the French king gave him. He was still true to the policy of the Dover Treaty, which his brother had abandoned, and still watched his opportunity to employ force for the restoration of his Church. All this was fully understood, and his enemy, Shaftesbury, was implacable.
