Well, today the guards are still some kind of bodyguards... but it's mainly a sign of sympathy - as Switzerland has been a leading force of reformation, what cost the catholic church much of its influence in Europe at the end of the medieval age.
As a consequence of occupation three states formed an agreement in 1291 giving birth to the country Switzerland (now consisting of 20 full and 6 semi-states) - this defence coalition against the earls of Habsburgs led to several battles. The troops, now appearing under the sign of the state of Schwyz (giving name and flag) fought several battles against opponents - making Swiss mercenaries a famous and expensive war equipment until 1515.
Swiss mercenaries also fought in northern Italy (Milan was under Swiss control), especially during the milanese wars. The pope used mercenaries as protection squad. After a break due to reformation, Switzerland sent again guards as bodyguards for the pope - their uniform is tradition. Their equipment is modern, the Swiss guards are part of the Swiss army - the only situation they are allowed to served for Another Country.
