# Multiple lines of text in math mode

One of the assumptions in my paper requires a long line of text. Is there a way to format this nicely? I'd like to keep it in math mode so that it looks the same as the other assumptions and I can refer to it with a label.

Thanks!

\begin{align*}
\text{The joint distribution of $(D, M_1, M_2, \theta)$ admits a bounded density with respect to the product measure of the counting measure on the set $\{0,1\}$ and the Lebesgue measure on $\mathcal{M}_1 \times \mathcal{M}_2 \times \Theta$. All marginal and conditional densities are also bounded.} \tag{A1}
\end{align*}

Single line equations should never be in align (even without the \text requirement).

You could use

$$\parbox{.7\textwidth}{The joint distribution of (D, M_1, M_2, \theta) admits a bounded density with respect to the product measure of the counting measure on the set \{0,1\} and the Lebesgue measure on \mathcal{M}_1 \times \mathcal{M}_2 \times \Theta. All marginal and conditional densities are also bounded.} \tag{A1}$$


Although probably I'd look at using an environment defined with \newthorem rather than math mode for this.
