Be not deceived, my brethren: If anyone follows a maker of schism [i.e., is a schismatic], he does not inherit the kingdom of God; if anyone walks in strange doctrine [i.e., is a heretic], he has no part in the Passion [of Christ]. Take care, then, to use one Eucharist, so that whatever you do, you do according to God: For there is one flesh of our Lord Jesus Christ, and one cup in the union of his blood; one altar, as there is one bishop, with the presbytery and my fellow servants, the deacons (Letter to the Philadelphians 3:3-4:1 [A.D. 110]).
St Ignatius taught that there is only one alter and one bishop in the letter to the Phiadelphians.( There should be a number of bishops with equal status in Church, not only one bishop which is infalliable has special authority, like catholic church!!
What does 'ONE alter' and 'ONE bishop' mean in the letter to Phildeplphians? How do Orthodox Christians understand 'One altar' and 'one bishop'?
