this is strictly my opinion others may argue

lucchese controlled everyone you mentioned, he controlled the archbishop, keinzig ("swiss banker dude"), don altobello. after mike invested the money into the church the full control vote had to be ratified in rome by the pope himself. with the pope "suddenly" taking illness and later dying there goes the pope's vote for michael and "all bets are off". costing mike his investment, or so it seems.
