QUOTE : Why did Christ teach from Peter's ship?<br /><br />By this He showed that the true doctrine is preached only from that Church of which Peter is the head (Jn 21:15), which is here represented by his ship. Amid storms of persecution Jesus has preserved and will preserve this ship, His Church, until the end of time (Mt 16:18). Peter still guides the bark in the unbroken line of his successors, and Jesus still teaches from this ship the same doctrine through the bishops and priests, as His co-operators, with whom He has promised to remain to the end of the world (Mt 28:20). (Fourth Sunday After Pentecost)
