4 The parties at Antioch to unite.
But that we, and they who have ever remained in communion with us, hold this faith, we think no one of yourselves nor any one else is ignorant. But since we rejoice with all those who desire re-union, but especially with those that assemble in the Old [church], and as we glorify the Lord exceedingly, as for all things so especially for the good purpose of these men, we exhort you that concord be established with them on these terms, and, as we said above, without further conditions, without namely any further demand upon yourselves on the part of those who assemble in the Old [church], or Paulinus and his fellows propounding anything else, or anything beyond the Nicene definition.
