Never said it wasn't.
Of course the Gospel and salvation through Christ are for every man.
It is, however, a cornerstone of Western civilization, a vital part of the unique culture of European civilization and White persons.
Which is why the powers that be are so hell bent on wrecking the church and the Word.
Paul has harsh words for the people that seek to do that:
For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe.
For ye, brethren, became followers of the churches of God which in Judaea are in Christ Jesus: for ye also have suffered like things of your own countrymen, even as they have of the Jews:
Who both killed the Lord Jesus, and their own prophets, and have persecuted us; and they please not God, and are contrary to all men:
Forbidding us to speak to the Gentiles that they might be saved, to fill up their sins alway: for the wrath is come upon them to the uttermost.
1 Thessalonians 2 13:16

Where is @TER when you need him? The Orthodox church, which is really a family of churches and basically everybody except the RCC, did indeed spread around the world. When Ethiopia was invaded by Italy the first time they reached out to Russia as fellow Orthodox believers.
