Ukuzalisa izilwane zasemapulazini ukuthuthukisa ngamabomu umhlambi wezinkomo noma ukuthuthukisa izici ezithile ezifana nokwandisa ubisi. Ukuthuthukiswa kwe-genetic kwenzeka uma abazali bakhe bekhetha kangcono. Njengoba izinkomo zakha umhlambi wezimbuzi, kulandela ukuthi izinkunzi ezisetshenziselwa ukuthola izinkomo ezikhulelwe zithole ukunakekelwa kwemfuyo. Note that a variety of theories have been concocted over the years on the part of the Church’s opponents to attempt to explain her origin—or explain it away one might say. The most common such theory alleges Catholicism came into being in the fourth century, around the time the Emperor Constantine the Great legalized Christianity throughout the Roman Empire. This theory holds that a large portion of the Christian Church eventually became corrupted by pagan influences due to a huge influx of converts. Of course, the insurmountable obstacle to this theory is the presence of Catholic doctrine in the ecclesiastical writings that predate Constantine, and the historical writings of the Early Church Fathers demonstrate this in a powerful way.
