Catechisms do not even discuss the form of the earth and certainly do not teach earth is a globe. So that concern is non existent. Not sure what a "doctrinal manual" is, but most of these will not discuss much on the subject, either. Church docuмents skim the subject somewhat ...
Which is what I was saying. I haven't seen any indication the Church has a doctrine about this, any more than the Church has a doctrine about the nature of clouds, the number of chromosomes in humans, the speed of light, or the vast majority of things under the field of science.
but shine in their fullness when viewed in light of the teachings of Scripture and the Fathers. St. John Chrysostom, St. Jerome, Methodius, Lactanctius, Severian, Cosmos, and a whole host of Fathers and saints were flat earthers as their writings prove. Not one Father of the Church teaches earth is a globe using Scripture. Not one.
Not one? Even if that were true, which I rather doubt, would that matter? I bet not one Father of the Church taught about DNA, and yet DNA does exist.
But if the Church doesn't teach a doctrine, it doesn't really matter if you think Scripture or some number of Fathers say it. Protestants of various flavors think the Scriptures teach all sorts of things, and they can often even point to some Church Fathers in support. That doesn't make what they think a teaching of the Church.
