12 According to the almost unanimous opinion of believers and unbelievers alike, all things on earth should be related to man as their center and crown. But what is man? About himself he has expressed, and continues to express, many divergent and even contradictory opinions. In these he often exalts himself as the absolute measure of all things or debases himself to the point of despair. The result is doubt and anxiety. The Church certainly understands these problems. Endowed with light from God, she can offer solutions to them, so that man's true situation can be portrayed and his defects explained, while at the same time his dignity and destiny are justly acknowledged. For Sacred Scripture teaches that man was created "to the image of God," is capable of knowing and loving his Creator, and was appointed by Him as master of all earthly creatures that he might subdue them and use them to God's glory. "What is man that you should care for him? You have made him little less than the angels, and crowned him with glory and honor. You have given him rule over the works of your hands, putting all things under his feet" (Ps. 8:5-7). But God did not create man as a solitary, for from the beginning "male and female he created them" (Gen. 1:27). Their companionship produces the primary form of interpersonal communion. For by his innermost nature man is a social being, and unless he relates himself to others he can neither live nor develop his potential. Therefore, as we read elsewhere in Holy Scripture God saw "all that he had made, and it was very good" (Gen. 1:31).
