Ambrose countered Arian's heresy(which Islam is heavily inspired by).
He is a devout Catholic and one of the first Doctors of the Church. Those men and women of Christ who have contributed great writings and theological understanding to His flock.

The full context of this is countering claims from Arian and his sect.
I will translate the gist of his wording in that one quote into a modern way:
"Makes you wonder if they(Arianists) who lied about the scripture also lie about the ancient Greek not including those words. It's obvious they did it to blaspheme and justify their false position"
