J.H. Merle d’Aubigné:

The residence of Tyndale and his friends in foreign countries, and the connections there formed with pious Christians, testify to the fraternal spirit which the reformation then restored to the church. It is in Protestantism that true catholicity is to be found. The Romish Church is not a catholic church. Separated from the churches of the East, which are the oldest in Christendom, and from the reformed churches, which are the purest, it is nothing but a sect, and that a degenerate one. A church which should profess to believe in an episcopal unity, but which kept itself separate from the episcopacy of Rome and of the East; and from the evangelical churches, would be no longer a catholic church; it would be a sect more sectarian still than that of the Vatican, a fragment of a fragment. The church of the Saviour requires a truer, a diviner unity than that of priests, who condemn one another. It was the reformers, and particularly Tyndale, who proclaimed throughout Christendom the existence of a body of Christ, of which all the children of God are members. The disciples of the reformation are the true Catholics (The Reformation in England, Vol. I, p. 367).
