At the time, of which we are speaking, the doctrines of the high church, which are generally considered to incline to those of the Roman Catholics, more than the doctrines of the low church, were in their zenith; and in France, where the ultramontane principles on the power of the Pope had always been discountenanced, the disputes of Jansenism were supposed to reduce it very low. On each side, therefore, the time was thought favourable to the project of Reunion. It was also favourable to it, that, a few years before this time, an event had taken place, which naturally tended to put both sides into good humour. On the occasion of the marriage of the Princess Christina of Wolfenbuttell, a Lutheran, with the archduke of Austria, her court consulted the faculty of theology of the University of Helmstadt, on the question, "Whether a Protestant Princess, destined to marry a catholic prince, could, without wounding her conscience, embrace the Roman Catholic religion?" The faculty replied, that, "it could not answer the proposed question, in a solid manner, without having previously decided, whether the catholics were, or were not engaged in errors, that were fundamental, and opposed to salvation; or, (which was the same thing), whether the state of the catholic church was such, that persons might practise in it, the true worship of God, and arrive at salvation." This question the divines of Helmstadt, discussed at length; and concluded in these terms: "After having shown, that the foundation of religion, subsists in the Roman Catholic religion, so that a person may be orthodox in it, live well in it, die well in it, and obtain salvation in it, the discussion of the proposed question, is easy. We are, therefore, of opinion, that the most Serene Princess of Wolfenbuttell, may, in favour of her marriage, embrace the catholic religion." This opinion is dated the 28th of April 1707, and was printed in the same year at Cologne. The Journalists of Trevoux inserted both the original and a French translation of it in their journal of May, 1708.
