What happens when you tell your dad about your day and your interests and your hopes and dreams and fears? Sometimes he talks with you, sometimes he hugs you hard and kisses you gently on the cheek, sometimes he gets something done outside in the world. If you just got a bad boo-boo, he may kiss your forehead and get you some peroxide and later a band-aid, and his words matter not necessarily because they’re good information on how to deal with your boo-boo but because they’re the words he’s chosen to say to you.
Now, what happens when you pray? He speaks when you hear the holy Scripture read, he feeds you and empowers you and embraces you, and he hears your prayer and providentially does as he knows to do, because he loves you as his own adopted child. Often, he does this in the divine liturgy and in the love that Christ commanded members of his Body to have for one another – the Church is Christ’s beloved Bride, and consequently also his own Body, as Adam said too of his wife:
This at last is bone of my bones
and flesh of my flesh;
she shall be called Woman,
because she was taken out of Man.
Conversation? For sure, but God does a lot more than zap you with information. Isn’t this the personal (but not individualistic) God revealed in holy Scripture, the eternal Word, the Truth who is come to us as a person? This is what we encounter in the reading of God’s word (often explained to us in a sermon) and the administration of the Sacraments and everything that flows from that.
