Kizito while Speaking at Saint Mary's Cathedral Rubaga during mass, the Catholic Archbishop said many Christians don't tithe and this affects projects by the church.
"Whenever we ask for tithe, everyone gives only what they have at that time. But the Bible says a tenth of whatever you earn belongs to the church," said Archbishop Lwanga.
"Give me your support as I front this proposal because it is good for us. Aren't you tired of putting money in the baskets all the time?"
Archbishop Lwanga said he wanted Uganda to go the Germany route where Germans who are registered as Catholics, Protestants or Jews have a church tax (Kirchensteuer) of 8-9 percent deducted from their annual income.
The church tax is collected by the government and channeled to the respective faiths.
"I was told Germans make agreements with their government to deduct monthly tithe from their salaries and forward it to the church and this money they use to build and renovate their churches," he added.
