Then go for the option where all the voting happens at one step based on preference. If you still want a best of two you can have the primary election earlier in the year with a score vote tally, and the two candidates that have the highest scores votes from that process then go into a head to head FPTP style for the general election.
For the record both Alaska and Maine are currently using an Alternative Voting system as well as many countries in Europe. Australia also uses an Alternative Voting system. So it can be done successfully in many countries without issue.
Jesus basically came in to say: just follow the commandments, love one another, love your enemy as yourself, don’t be greedy and selfish, and you guys don’t have to keep doing those self-imposed rules the Israelites made themselves do like don’t eat pork or shell fish, etc.
Israelites believed that they were supposed to be purists about everything they do to some degree and saw being a purist as being holy; such as never mixing two different kinds of fabric together or don’t raise your goats with your sheep. Jesus said you don’t need to be a purist about all this unimportant stuff, but be good people.
