John Wycliffe, who was a precursor to the reformation, also believed in an invisible church made of the predestinated elect. Another precursor of the reformation, Johann Ruchrat von Wesel believed in a distinction between the visible and invisible church. Pietism later took this a step further, with its formulation of ecclesiolae in ecclesia ("little churches within the church"). Non-distinction Roman Catholic theology, reacting against the protestant concept of an invisible Church, emphasized the visible aspect of the Church founded by Christ, but in the twentieth century placed more stress on the interior life of the Church as a supernatural organism, identifying the Church, as in the encyclical Mystici corporis Christi of Pope Pius XII, with the Mystical Body of Christ. In Catholic doctrine, the one true Church is the visible society founded by Christ, namely, the Catholic Church under the global jurisdiction of the bishop of Rome. This encyclical rejected two extreme views of the Church: (1) A rationalistic or purely sociological understanding of the Church, according to which it is merely a human organization with structures and activities, is mistaken. The visible Church and its structures do exist but the Church is more, as it is guided by the Holy Spirit: Although the juridical principles, on which the Church rests and is established, derive from the divine constitution given to it by Christ and contribute to the attaining of its supernatural end, nevertheless that which lifts the Society of Christians far above the whole natural order is the Spirit of our Redeemer who penetrates and fills every part of the Church. (2) An exclusively mystical understanding of the Church is mistaken as well, because a mystical "Christ in us" union would deify its members and mean that the acts of Christians are simultaneously the acts of Christ. The theological concept una mystica persona (one mystical person) refers not to an individual relation but to the unity of Christ with the Church and the unity of its members with him in her. This is where we can find direct contrast to Christian philosophy like the preachings of Rev.Jesse Lee Peterson, yet the personification is similar. There is another view, that contrasts these two school-of-thought, and that is from Albert Eduard Meier, as he includes Electric Theory in his teachings, similar to Creationism. Eastern Orthodox theologian Vladimir Lossky too characterizes as a "Nestorian ecclesiology" that which would "divide the Church into
