The distinctive prayer in Orthodox Christianity (of course, we share the Lord’s Prayer) is the Trisagion (“thrice holy”), which includes this:
Most Holy Trinity, have mercy on us. Lord, cleanse us from our sins. Master, pardon our transgressions. Holy One, visit and heal our infirmities for Your name’s sake.
29-30 years ago, that was part of what set the hook, compelling me toward Orthodoxy, as my church didn’t know this distinction, but my heart did, and so did Orthodoxy.
