Landgrave, he foresaw little difficulty in conquering his own conscience.

The Prince of Orange, it is evident, was placed in such a position, that
it would be difficult for him to satisfy all parties. He intended that
the marriage, like all marriages among persons in high places at that
day, should be upon the "uti possidetis" principle, which was the
foundation of the religious peace of Germany. His wife, after marriage
and removal to the Netherlands, would "live Catholically;" she would be
considered as belonging to the same Church with her husband, was to give
no offence to the government, and bring no suspicion upon himself, by
violating any of the religious decencies. Further than this, William, who
at that day was an easy, indifferent Catholic, averse to papal
persecutions, but almost equally averse to long, puritanical prayers and
faces, taking far more pleasure in worldly matters than in ecclesiastical
controversies, was not disposed to advance in this thorny path. Having a
stern bigot to deal with, in Madrid, and another in Cassel, he soon
convinced himself that he was not likely entirely to satisfy either, and
thought it wiser simply to satisfy himself.

Early in 1560, Count Gunther de Schwartzburg, betrothed to the Prince's
sister Catharine, together with Colonel George Von Holl, were despatched
to Germany to open the marriage negotiations. They found the Elector
Augustus already ripe and anxious for the connexion. It was easy for the
envoys to satisfy all his requirements on the religious question. If, as
the Elector afterwards stated to the Landgrave, they really promised that
the young lady should be allowed to have an evangelical preacher in her
own apartments, together with the befitting sacraments, it is very
certain that they travelled a good way out of their instructions, for
such concessions were steadily refused by William in person. It is,
however, more probable that Augustus, whose slippery feet were disposed
to slide smoothly and swiftly over this dangerous ground, had represented
the Prince's communications under a favorable gloss of his own. At any
rate, nothing in the subsequent proceedings justified the conclusions
thus hastily formed.

The Landgrave Philip, from the beginning, manifested his repugnance to
the match. As soon as the proposition had been received by Augustus, that
potentate despatched Hans von Carlowitz to the grandfather at Cassel. The
Prince of Orange, it was represented,
