The basic rule of thumb is that modesty requires not giving oneself a title. While a title may be noted in correspondence for identification purposes, the signer does not include a title in his signature. So, in the following examples, the first line is the signature and the following line(s) are the typed identification.
Priest signature:
Francis X. O’Hara
The Rev. Francis X. O’Hara, S.J.
Bishop signature:
+Paul M. George
The Most Rev. Paul M. George
Bishop of Metropolis
