during the Hitler era, the Lutherans in Germany did not refuse communion to those who belonged to the Nazi party.
The Catholic Church in Germany excommunicated the Nazis, and excommunicates cannot receive Holy Communion.
Another instance was when St. Ambrose of Milan (346-395 A.D.) excommunicated the Christian Roman emperor Thedosius I, who, out of excessive zeal and to make an example, ordered the massacre of 7,000 innocent spectators in an amphitheater of barbaric gladiatorial games in Thessalonica (390 A.D). St. Ambrose wrote him:
It grieves me that you, who were an example of singular piety, who exercised consummate clemency, who would not suffer individual offenders to be placed in jeopardy, should not mourn over the destruction of so many innocent persons … I dare not offer the Sacrifice if you determine to attend.
After 8 months of public penance, Theodosius was readmitted to the Church. St. Ambrose's said at his funeral 4 years later:
I loved him because, divesting himself of his regal state, he wept publicly for his sins and asked for pardon with groans and tears. I loved him because, Emperor as he was, he was not ashamed to do the public penance from which many of low degree shrink, and because he deplored his sin every day he lived.

Saint Ambrose barring Theodosius from Milan Cathedral:
Wakati wa utawala wa Hitler, wafuasi wa dini ya Kilutheri nchini Ujerumani waliwaunga mkono wafuasi wa chama cha Nazi. Kanisa Katoliki nchini Ujerumani liliwafukuza Wanazi katika ushirika, na watu waliotengwa na ushirika hawawezi kupokea Mkutano Mtakatifu. Ambrose wa Milan (346-395 KK) alimwondoa Mkristo Thedosius I, ambaye kwa sababu ya bidii ya kupita kiasi na ili kutoa mfano, aliamuru mauaji ya watazamaji wasio na hatia 7,000 katika ukumbi wa michezo ya gladiatorial huko Thesalonike (390 KK). "Mtakatifu Ambrose alimwandikia hivi: ""Inanihuzunisha kwamba wewe, ambaye ulikuwa mfano wa uaminifu wa pekee, ambaye ulitumia huruma kamili, ambaye haungevumilia wahalifu mmoja-mmoja kuwekwa hatarini, hupaswi kuomboleza uharibifu wa watu wengi wasio na hatia... Mimi siwezi kutoa dhabihu ikiwa unaamua kuhudhuria." Baada ya miezi minane ya toba ya umma, Theodosius alikubaliwa tena katika Kanisa. "Mtakatifu Ambrose alisema katika mazishi yake miaka minne baadaye: ""Nilimpenda kwa sababu, akijiondoa katika hali yake ya kifalme, alilia hadharani kwa dhambi zake na kuomba msamaha kwa kuugua na machozi.""" Nilimpenda kwa sababu, kama Mfalme, hakuwa na aibu kufanya toba ya umma ambayo wengi wa kiwango cha chini hujificha, na kwa sababu aliomboleza dhambi yake kila siku aliishi.
