In 1827, when the Catholic Church had a new concordat with the
United Kingdom of the Netherlands, Archbishop van Santen attended a series of meetings with Monsignor Capaccini, the
papal nuncio of the
Roman Catholic Church, in an attempt to reconcile the two churches. C.B. Moss says: "The first conference was entirely occupied by compliments paid by Capaccini to the '
Jansenists' in general and to Archbishop van Santen in particular; he praised their steadfastness in a
Protestant country, their firm adhesion to Rome, the stand they had made against lax
casuistry, the carefulness and prudence of the archbishop." During the second meeting, van Santen refused to sign the
Formulary of Alexander VII that was presented by Capaccini, thus condemning five propositions purportedly contained in the
Augustinus and affirming the authority of the
pope. According to C.B. Moss, van Santen replied: "I know that the Five Propositions, as condemned, are not contained in that book; how can I, then, as an honest man and a Christian, sign a declaration which denies the fact? I must obey God and my conscience, even in the Pope and the whole Church are misinformed." Purportedly asking, "Is Catholic unity to be maintained by perjury?", van Santen is likened by many to
Martin Luther, for their stands against the hierarchy of the
Roman Catholic Church. C.B. Moss concludes: "If [van Santen] had accepted the Formulary, and his two suffragans with him, their names would have been acclaimed throughout the Roman Catholic world…as the men who by their submission had healed the '
Jansenist schism'; …And yet he would not, for any advantage in this world or the next, declare that to be true which he was quite sure was false. He knew that conscience has a more binding authority than either Pope or Church." On 4 March 1853
Pius IX negotiated with the Dutch Government to establish a new hierarchy in the
Netherlands, with a
Roman Catholic archbishop in
Utrecht and four suffragan bishops in
Haarlem,
's-Hertogenbosch,
Breda and
Roermond but with no boundaries corresponding to the sees erected by the
Roman Catholic Church in 1559. Van Santen, together with Bishop of Haarlem Henricus Johannes van Buul, issued a formal protest against the rival bishops in the sees they already occupied. ==Protest of the Immaculate Conception==
