On which 2 doctrines does the Magisterium, the Pope and Bishops, proclaim by a
definitive act infalible?

i believe its the indians

the hyksos invasion. the hyksos were able to attack egypt successfully because of their skills in using bronze weapons, composite bows and the use of the horse and chariot during the invasion. although the egyptians depict a barbarian-type overthrow, the truth is the seizure was likely a relatively peaceful one.

i'll write a docs for you. hold on for a moment
