WHAT ABOUT SALVATION?

Do not separate from the Church ... A sheep outside the Church is the snare of the wolf.
St. Eusebius of Caesaria

The distinctive mark of the Church is to belong to the Church outside which there is no salvation. On the contrary, he who leaves the Church walks in darkness: he is a heretic.
Origen

Whosoever would be saved, let him come into this House. Let no one talk himself out of it; let no one deceive himself: outside this House, that is, out of the Church, no one is saved.
Origen

You must seek Him in the Church.
Origen

But when the unbelieving, who do not obey the truth but are disobedient and unrighteous, shall have been filled with adulteries and fornications and filthiness and covetousness and unlawful idolatries, there shall be anger and wrath, tribulation and anguish, and in the end everlasting fire shall possess such men.
St. Theophilus of Antioch

The Church of God, walking straight in the right and royal road, has condemned all the rest as by-paths.
St. Eusebius of Caesaria
