So, how is the leadership of your church chosen? Every non-Catholic Christian denomination uses some sort of committee to determine who their Pastor will be.
Denominations, such as Baptists, vote also, on who their leadership will be.
So..., Roman Catholics vote on who its leader will be, and use smoke to communicate that a leader has been chosen.
What does picking leadership have to do with blasphemy?
Again, I don’t see how you are connecting the two.
I myself am very against the traditions of man and always go back the he scrpiture. Christ said he never changed, yet the Church it self has changed many times, adding to what is needed, required, etc. This just isn't against the Catholic Church, it goes for the Orthodox faiths and Anglican faiths as well.
If the theif on the cross and the thousands mentioned in the book of Acts can be saved by declaring Christ is the Lord, then it can still happen today.
