It is debatable whether Cromwell was truly committed to the Protestant Reformation or simply carrying out orders. His primary focus was on dismantling the monasteries, because they were very wealthy, and confiscating their property freed up one-third of the land in England which could be resold to Cromwell’s allies.
The Reformation proper did not begin until the reign of Edward VI when the Lord Protector Edward Seymour introduced more radical protestant ideas. A new English prayer book was released, vestments and altars were banned and allowed priests to marry. Cromwell’s Reformation by comparison did the bare minimum to free Henry from the constraints of the Catholic Church and build new political ties across Europe.
Cromwell’s Reformation did not go very far. He was probably just following orders and looking for financial gain and political alliances.
