In fine, in his _Votum pro pace_[607], he proves by a long series of passages from the Fathers, that the invocation of saints was used by the ancient Church, and therefore cannot be treated as idolatry; that there is no law in the Gospel against the use of Images in Churches, that it cannot be said they are forbid by the law of nature, and that in the times of St. Ambrose and St. Augustine the relics of Martyrs were honoured in the Church. He defends in several places Praying for the Dead, which was practised in all the Churches of the East, as well as of the West[608]: he proves that the ancient Church prayed for the Dead, and that St. Augustine[609] regarded the opposers of this practice as heretics. He maintains[610] that every ancient liturgy has prayers for the Dead, and that as Tertullian relates, they were used in all the Churches in his time. He asserts[611], that the Jews knew and admitted of a Purgatory. One of the articles which made most noise in the beginning of the grand Schism in the sixteenth Century was that of justification, Grotius declares[612], that the more he examined the Scriptures, the greater agreement he discovered between them and the tradition of the Roman Church concerning justification. He was persuaded that it had the same idea of the Catholic Church mentioned in the Creed, as the ancients entertained. He would have men submit to the decisions of general councils[613]; and maintains that a pious and peaceable man ought not to contradict them when their decrees are received by almost all the Churches, especially those which were founded by the Apostles. He means no doubt the Council of Trent.
