That's some claim, ealgone. Please direct us to the "Roman Catholic apologists" who 'admit that the Immaculate Conception is not supported "in the Word." Thanks in advance.
No direct or categorical and stringent proof of the dogma can be brought forward from Scripture.

No direct or categorical and stringent proof of the dogma can be brought forward from Scripture.To say that there is "no direct or categorical and stringent proof" of the Immaculate Conception is not the same as saying that the Immaculate Conception "is not supported" in the Word.
To illustrate the difference, one could still find "support" for the dogma of the Trinity, even though "no direct or categorical and stringent proof" of the Trinity can be brought forward.
