"If people want a sense of purpose they should get it from their archbishop. They should certainly not get it from their politicians"

In this quote, Harold MacMillan is suggesting that people should seek to their spiritual leaders, particularly their archbishop, for a sense of function instead of depending on politicians. He thinks that politicians are not the appropriate source for discovering a sense of function in life. This could be interpreted as a criticism of political leaders and their ability to supply assistance and direction to the public. MacMillan might be indicating that political leaders are more concentrated on their own agendas and may not have the moral authority or knowledge to assist people in discovering their function. In general, this quote highlights the importance of seeking assistance from trusted and respected figures, such as spiritual leaders, in discovering a sense of function in life.
