There is a long tradition in Judaism of engaging first in religious practices and letting matters of faith come later. In the book of Exodus, after Moses has received the Commandments from God, he begins to instruct the Jewish people in the law; their immediate response is na’aseh v’nishma (נַעֲשֶׂ֥ה וְנִשְׁמָֽע): "We will do first and understand afterwards".
Do first / understand later as applied to parenting. You can act first by pulling the child out of a dangerous situation, and then explain to them why you did that.
"Deed over creed" is a terse way of describing this idea from The Blessing of a Skinned Knee by Wendy Mogel.
This is also present in eastern traditions as in the Karate Kid movie and in the zen tradition where a teacher gets you to do things that incongruous, and then later you understand what the point was.
First make sacred pact: I promise to teach Karate. You promise to learn. I say, you do. That's your pact. Deal? Deal
