When you read “dogmatics” with Bavinck think systematic theology. When you see “dogma,” think doctrine, or truth.
[O]ne who clings to the truth of religion cannot do without dogma and will always recognize in it an unchanging and permanent element. A religion without dogma, however vague and general it may be, without say, faith in a divine power, does not exist, and a nondogmatic Christianity, in the strict sense of the word, is an illusion and devoid of meaning. Opposition to dogma is not resistance to dogma as such, for ‘unbelief has at all times been most dogmatic” (Kant), but to certain specific dogmas with which people no longer agree. —Herman Bavinck, Reformed Dogmatics
