Based on reading what did puritan leaders probably force all colonists to do

The answer is attend church services.

The Puritans were fiercely religious. Their faith was a combination of Calvinism and Protestantism. They were highly devout and their entire lifestyle revolved around practicing their faith and worshiping God. They believed that it was a sin not to attend church and they wanted the colonies to be pure and righteous so they probably inflicted their faith on them and forced them to go to church.
