I’ve just read Bishop Athanasius Schneider’s little book Dominus Est. It is reviewed here by Alcuin Reid

It is an important book giving fascinating evidence from the documents of the Church, the Apostolic Fathers and the tradition of the Church both East and West for the reception of Holy Communion on the tongue kneeling.
It has certainly influenced my thinking, and I will be recommending that the faithful show more reverence when coming to communion. Reminding them of the need to make an act of reverence before reception and also encouraging them to receive on the tongue.
