You can judge the quality of their faith from the way they behave. Discipline is an index to doctrine.
TertullianBut all the other frenzies of passions-impious both toward the bodies and toward the sexes-beyond the laws of nature, we banish not only from the threshold, but from all shelter of the Church, because they are not sins, but monstrosities.
TertullianIt is not consistent with truth that a man should sacrifice half of his stomach only to God-that he should be sober in drinking, but intemperate in eating. Your belly is your God, your liver is your temple, your paunch is your altar, the cook is your priest, and the fat steam is your Holy Spirit; the seasonings and the sauces are your chrisms, and your belchings are your prophesizing...[such] a grossly- feeding Christian is akin to lions and wolves rather than God. Our Lord Jesus called Himself Truth and not habit.
TertullianWhat is nobler than to tread under foot the gods of the nations, to exorcise evil spirits, to perform cures, to seek divine revelations, and to live to God? These are the pleasures - these are the spectacles - that befit Christian men.
TertullianBut now inquiry is being made concerning these issues. First, can any believer enlist in the military? Second, can any soldier, even those of the rank and file or lesser grades who neither engage in pagan sacrifices nor capital punishment, be admitted into the church? No on both counts.
TertullianDo you not know that you are Eve? The judgment of God upon this sex lives on in this age; therefore, necessarily the guilt should live on also. You are the gateway of the devil; you are the one who unseals the curse of that tree, and you are the first one to turn your back on the divine law; you are the one who persuaded him whom the devil was not capable of corrupting; you easily destroyed the image of God, Adam. Because of what you deserve, that is, death, even the Son of God had to die.
TertullianIt is a fundamental human right, a privilege of nature, that every man should worship according to his own convictions.
TertullianI revere the fullness of His Scripture, in which He manifests to me both the Creator and creation. In the gospel moreover, I discover a Minister and Witness of the Creator, even His Word.
TertullianIn our case, murder being once for all forbidden, we may not destroy even the foetus in the womb, while as yet the human being derives blood from other parts of the body for its sustenance. To hinder a birth is merely a speedier mankilling; nor does it matter whether you take away a life that is born, or destroy one that is coming to the birth. That is a man which is going to be one; you have the fruit already in the seed.
Tertullian
