84 When We fondly call you to the unity of the Church, please observe that We are not inviting you to a strange home, but to your own, to the abode of your forefathers. Permit Us, then, to long for you all "in the heart of Christ Jesus," (35) and to exhort you all to be mindful of your forefathers who "preached God's word to you; contemplate the happy issue of the life they lived, and imitate their faith." (36)
