Alright, my thougts on this are that although it is not personally addressed to a Church we see the counciling of one who is to lead a Church, and we see both what the leader is expected to do & what those to whom he teaches should do in submission to that godly authority. We also gain some very valuable theology from 1 & 2 Timothy. It is sound wisdom and advice. It may be that the commands specific to Timothy as a leader may not apply to you (since all believers, as Paul says, have different offices & callings) but the principles are always applicable, not to mention the majority of the Epistle not specific to Timothy (which involves general doctrine & instruction). Also at 1 Timothy 3:1 Paul says that if one desires to be a leader (an overseer), that he desires a good thing. Thus all the advice and commands given to Timothy are also good instruction to those who would aspire to the virtues of leadership in the Church. That's the purpose of the Pastoral Epistles (including Titus). So it can indeed speak to the Church, though it probably qualifies for those who are more mature in their walk, who have moved past the milk of the word, since Paul does not offer the basics of the faith, but sound advice and commands to a leader in the Church.
I hope that helps to answer your question.
God Bless,
