The dating to winter seems to have been a calculation derived from Easter via the annunciation (and ultimately Passover).
Nothing about the date, season, approximate time of year etc has anything to do with pagan customs or marketing ploys.
I put an a retractable pergola in my back yard that can be set to let the sun through to my vegetables, or to block the sun when I am gardening on especially intense days. I also made it pretty and within building codes so that my neighbors appreciate it, rather than object.
It protects me from sunstroke. It allows me to plant vegetables that prefer less sun. It pleases and appeases the neighbors. It appreciates the value of my house. It pleases me.
One project with multiple goals. It's not hard. Quit treating the ancients like they were simpletons.
If the dating of Christmas was the result of theological speculation unconnected to any actual desire to create a major festival
Which dating of Christmas? Dec 25th? Jan 6th? Jan 7th? Jan 19th? Come on,
@Augustus. Just pause and think.
Christianity is an aggressive religion that seeks to spread across all cultures, convert the majority of the population and to impose its own culture influence ubiquitously. It does so through both confrontation (conquest and coercion) and appropriation (adaptation and assimilation). Sometimes it uses more of the carrot. Sometimes more the stick. Often both. This has been the case since Christianity gained power, and has remained the case through this very moment.
