Recently, the Korean Church has lost public trust in Korean society. Despite an abundance of Christian followers in Korea, the Korean Church has failed to make faithful believers. Under the current conditions, the Korean Presbyterian Church approaches this difficult situation by matriculating mature believers through catechism education. However, the possession of knowledge does not automatically translate to ethical behaviors. Knowledge and actions can be effectively harmonized in the context of Christian worship. In this same fashion, the Early Church tried to make sincere believers not merely by catechism education, but by liturgical catechesis. In this article, while studying the process and content of liturgical catechesis in the Early Church, I will argue that Early Church did not merely transmit knowledge, but developed practices to develop ethical beings through the congruence of education and practice. Through the use of Howard Gardner’s educational theory and Louis-Marie Chauvet’sunderstanding of sacramental symbols, I will prove the propriety and effectiveness of liturgical catechesis.
