Churchill had made his opinion on the question of Great Britain’s role in Europe very clear as early as 1930, when he published a newspaper article in support of Aristide Briand’s plan for the creation of a European federal union. Churchill wholeheartedly supported Briand’s idea, but he stressed that Great Britain could never be part of such a union because: “[…] we have our own dream and our own task. We are with Europe, but not of it. We are linked, but not comprised. We are interested and associated, but not absorbed.”
Context is everything. At that time he believed Britains’s future was with Commonwealth. The full article is available here;

As the Empire & Commonwealth diminished there is evidence he changed his mind.
We must build a kind of United States of Europe.. The structure of the United States of Europe, if well and truly built, will be such as to make the material strength of a single state less important.. If at first all the States of Europe are not willing or able to join the Union, we must nevertheless proceed to assemble and combine those who will and those who can.
Churchill - Zurich speech 1946
After the first British victory in the War, at Allemagne, Churchill wrote to his Foreign Secretary, Anthony Eden: “I must admit that thoughts rest primarily in Europe, the revival of the glory of Europe, the parent continent of the modern nations and of civilisation.” He then made a remarkably prescient comment, which I think would get him expelled from the Conservative Party today: “Hard as it is to say now, I look forward to a United States of Europe, in which the barriers between the nations will be greatly minimised and unrestricted travel will be possible.”
In his speeches in opposition, he seemed to indicate that he supported Britain becoming part of this Europe. He spoke at the Albert Hall, in May 1947, of the idea of a united Europe, “in which our country will play a decisive part,” and he argued that Britain and France should be the founder partners in this movement. He said: “If Europe united is to be a living force, Britain will have to play her full part as a member of the European family.”

The British Government have rightly stated that they cannot commit this country to entering any European Union without the agreement of the other members of the British Commonwealth. We all agree with that statement. But no time must be lost in discussing the question with the Dominions and seeking to convince them that their interests as well as ours lie in a United Europe.
