Archimandrite

The Archimandrite was a religious leader on Tara. He presided over the coronation of Prince Reynart (or, to be more accurate, the coronation of his android duplicate). He also performed the wedding ceremony between Prince Reynart and "Princess Strella". (TV: The Androids of Tara)

When he met the Seventh Doctor later, he did not marvel at the man's changed face and immediately knew who he was. (PROSE: The Trials of Tara)

Behind the scenes
The Archimandrite is the only character played by Cyril Shaps on Doctor Who to still be alive at the end of his appearance on the show.
