Abstract: Christianity proceeds from the ontologically defined unity of the human race as the addressee of the mission, but humanity as the addressee of the mission is not identical with the people of God in the person of the Church. On the contrary, the Church and humanity, throughout its history and to its end, are tragically disestablished. The addressee of the mission is not identical with the Church and is opposed to it as the outside world. Initially, the mission of the apostles is addressed to the external addressee, so the external mission is the original form of Christian missionary service. The article discusses the concept of the mission addressee through the ontological definition, as well as through its attitude toward the boundaries of the Church. The situation from the apostolic age to the present day shows the conventionality of the division of the mission into an external and internal one. Initially, the Church consists of people united by faith based on the living experience of communication and presence. In this regard, the article shows that any addressee of the testimony of this faith is an external addressee in relation to the apostolic mission. 

Abstract: The systematization of theological knowledge is a results of the reception of creedal content of Revelation in historical experience of the Church as a unique institution with a right for legitimate indoctrination, as well as authentic interpretation. The only source of this right is the Revelation itself. Correspondence of the results of such procedures with theological axiomatic is determined primarily by its succession and doctrinal intactness. The article examines the need in formation of the news mission strategies in modern world, which is a definitive motive for interpretation and systematization of the missionary aspects of Revelation. Namely the Revelation defines the method if reception, interpretation and systematization of the genuine content. At the present stage, the actualization of missionary aspects of the Revelation is preceded by a short, but extremely important process of the emergence and development of Orthodox missiology. This process carries an incomplete character, and its relevant results are interval, and this controversial. Therefore, the modern Orthodox missiology is in the stage of intense problematization of its research field and method. The paramount obstacle in development of this process is the ambiguous understanding of the role and theoretical-methodological status of the Orthodox missiology within the system of theological knowledge.

Abstract: The renewal of Orthodox Missiology in late XX - early XXI centuries happened mainly as an academic discipline. Along with that, results, obtained in the process of practical missionary ministry, cumulative integrated into theoretical mission studies. A gradual accumulation of empirical results took the Missiology to the qualitatively new theoretical level of research work. The need for a missiological actualization of ecclesiological problems of theology is associated with a high degree of dynamics of missionary service as going out the boundaries of the Church. In the article, the example, characterizing the specifics of the given process, is observed - actively used in this period, the concept of the missionary field, which precedes the transformation of the subject area of missionary activity in the research field of missiology. The subject-object relationship model is not applicable to missionary service, as it is implemented rather in the subject-subject paradigm. This determines the choice of the terminology of this study. The subject of the mission is expressed by the concept of the actor, and its object by the concept of the addressee of the mission, which determines the configuration of the research field of missiology.
