Hi. You seem to have started in a controversial area. Your edits are being reverted because they give undue weight to the minutiae of internal Catholic debate. A short statement on the Catholic position is fine, but a lengthy exposition is a sideline. Regardless, you need to talk about your proposed changes on the discussion page (e.g. talk:Use of fetal tissue in vaccine development). Guy (help! - typo?) 08:45, 14 August 2020 (UTC)
