That fight between the biggest church in Kikuyuland in the colonial days is back. Back then it was about female circumcision and traditional dances, today, it's something called mburi ya kiama.

what is is this ceremony? never heard an of my rela's , inlaws ,parents /grand parents mention it?

The church is right

They are simply discouraging this rite as it is very religious in nature with steps like sacrificing to ancestors

Kiamas do not practice a "homogeneous" philosophy and ideology, thats foolishness and idiocy. The famous GEMA founded by Jomo and publicly opposed by the same PCEA some years back as an "oathing secret demonic society" is an example of a "modern" political kiama idea, the church wanted everyone speaking english, saluting the Queen, etc made generalizations, and were paid in CASH by mzungu to destroy Jomos reputation even after independence, , kiamas objectives and missions vary, some are bad, and openly evil, like kiama kia nkoma, some FAKE, some for hunters kiama kia athii in shags, and they would have a lodge for meeting called nyumba ya athii, there is one still located in my village, but was changed to a primary school ages ago, some focus on God/Christian (eg a certain portion of "so called" njuri ncheke over the last 70 years or so is christian, and the methodist church from majuu in colonial times and DC's like the lamberts ensured they were inducted there by blessing njuri hence it is split into two by a shuka), some centered on views of historically GEMA people, "mburi" is a "fee", generalization of kiamas as ancestral worship centers and anti church is the same kind of ignorant talk that was used to kill our ancestors, and they seem hell bent on perpetuating.

This one the PCEA Church is going to lose and badly. Watch as the trickle out becomes a stampede.
