 Blacket was instrumental in introducing to Christ Church St Laurence all the elaborate High Church details in the style of the great Catholic architect, Augustus Welby Pugin.Sydney Evangelicals were shocked at the furnishing, the liturgy and the robed male choir, seeing it as "scandalous", and "papist".Later, Blacket was to be one of the architects to transform Greenway's St James in keeping with a High Church mode of worship (as it remains today).
