How far the proceedings of the Massachusetts Puritans were consistent with their original professions, with good faith towards the Mother Country, and with the principles of civil and religious liberty in the colony?
A careful recollection of the collateral events in England and those of the colony, at the time and after granting the Royal Charter, is requisite to a correct understanding of the question, and for the refutation of those statements by which it was misrepresented and misunderstood.
1.

The first question is, with what views was the Royal Charter granted, and with what professed views did the Governor and his associates leave England under the provisions of the Charter, and carrying it with them to Massachusetts Bay?
The theory of some New England historians is, that Puritanism in England was opposed to the Church of England, and especially to its Episcopal government--a theory true as respects the Puritanism of the Long Parliament after the second year of its existence, and of the Commonwealth and Cromwell, but which is entirely at variance with facts in respect to the Puritanism professed in England at the time of granting the Royal Charter to the Massachusetts Company in 1620, and for twelve years afterwards.

In the Millenary Petition presented by the Puritan party in the Church to James the First, on his coming to the throne, presbytery was expressly disclaimed; and in the first three Parliaments of Charles the First, during which all the grievances complained of by the Puritans were stated and discussed in the Commons, not the slightest objection was made to Episcopacy, but, on the contrary, reverence and fidelity in regard to it was professed without exception; and when the Long Parliament first met, eleven years after the granting of the Royal Charter to the Massachusetts Bay Company, every member but one professed to be an Episcopalian, and the Holy Communion, according to the order of the Church, was, by an unanimous vote of the Commons, ordered to be partaken by each member.

In all the Church, as well as judicial and political, reforms of this Parliament during its first session, Episcopacy was regarded and treated as inviolate; and it was not until the following year, under the promptings of the Scotch Commissioners, that the "root and branch" petition was presented to Parliament against Episcopacy and the Prayer Book, and the subject was discussed in the Commons.

The theory, therefore, that Puritanism in England was hostile to the Church at the period in question is contradicted by all the "collateral" facts of English history, as it is at variance with the professions of the first Massachusetts Puritans themselves at the time of their leaving England.
This is true in respect to Endicot himself, who was appointed manager of the New England Company, to succeed Roger Conant, and in charge of one hundred "adventurers" who reached Naumkeag (which they called Salem) in September, 1628--seven months before the Royal Charter granted by Charles the First passed the seals.
