The one fact I like to share about older churches that have these depictions of Christ: one can determine the type of church by observing Jesus’ benediction (his right hand). As seen below, his ring finger, pinky, and thumb are touching, representing a Catholic benediction because this formation reflects the Trinity. Orthodox benedictions (the other predominant church) have only the ring finger and thumb together.
Side note: this is my favorite church I have ever been to
