Not that it’s a poll question but I would guess a majority do not believe that.

It depends if your poll is of American Christians or worldwide Christians.

Also, if we speak historically, there is no comparison. Denying Mary’s Perpetual Virginity is an historical newcomer.

[Ransomed]

It would depend on who has more members, Orthodox + “Oriental” Orthodox + Catholics + some other smaller groups vs. Protestants + various nonDenominational Christians. I think Orthodox + Catholic alone has more, maybe Catholic by itself has more.

And yes, the truth of the matter, or any matter, isn’t dependant on how many people believe it or don’t.

Most Christians believe this -- all those in the Apostolic Church (Catholics, Orthodox, Copts, Armenians, Ethiopians, Assyrians etc), plus many Anglicans etc. -- fully about 2/3rd of Christians

however, as ransomed pointed out, this is not a numbers game

What is more relevant is how long have we believed this? And the answer is that we have believed this since the time of the Early Christians who were I think a little closer to the time when this happened than folks 1800 years later

The 3 main reformers: Luther, Calvin and Zwingli all believed this.

however, the third and fourth and fifth and sixth generations of reformatters slowly chipped away at all aspects of Christian belief
