While I embrace Jack's position entirely, I'm going to play Devil's Advocate and say "No, it is not welcome."
Because Systematic Theology at it's core relies on a "system of beliefs" that one must accept 'prime facie' before one can produce hermeneutically a response which addresses an OP's question. Whether it be about the nature of God, His Church, the Resurrection, the Trinity, or various doctrines which at their core express our fundemental beliefs, those beliefs are 'sacrosanct' and therefore 'outside' of the scope of discussion, even though an OP may give a scriptural example of why it isn't so.
Having said that, we all have a core of beliefs we consider sacrosanct: we are not here to 'defend' those beliefs(appologetics), but to derive from scripture the meanings contained within(exegesis), of which in the process we use certain methodologies(hermeneutics) which help to form a common framework for our discussion.
Our "theology" is going to leak into our answers, this is a given. Our hermeneutics will help us 'craft' those answers and find the widest range of support for our conclusions.
