The information about Cromwell's practice in his patronage of livings is from the last.

The book was dedicated to Cromwell.] But what of that Toleration of Dissent from the Established Church which he professed to be equally dear to him?
That Cromwell was faithful still to the principle of Liberty of Conscience, to the fullest extent of his past professions, there can be no doubt.

It may be more doubtful whether his past professions pledged him to a theory of Toleration as absolute as that which had been advocated eleven or twelve years before by Roger Williams and John Goodwin, and then adopted by the Army Independents generally, and which was still upheld by the main body of the Anabaptists.

The evidence, however, rather favours the idea that he had already been in sympathy even with this extreme theory of Toleration, and so that now, though he had bitterly disappointed his old Anabaptist associates by declaring himself for the Civil Magistrate's Authority in matters of Religion, he still cherished the extreme theory of Toleration as it might be applied round about his Established Church.

In his heart, I believe, he was for persecuting nobody whatsoever, troubling nobody whatsoever, for mere religious heresy, even of the kinds he himself most abhorred.
