Those times have/are changing under Erdogan. Turkey is turning away from secularism to Islamism under their current leader, who some say he has aspirations of becoming the head of a new Islamic Caliphate.
Today, Turkey's government under Erdogan is no ally of Russia's government under Putin.
Your argument is ridiculous. Putin’s government is a close ally of Iran. Iran has a far more extreme Islamic government than Turkey. Russia is fighting in Syria on behalf of Iran. So your idea that Putin is opposed to be Islamic nations is just plain wrong.
You are trying to make Putin some kind of Christian hero. That is a misguided effort.
