Contradiction with John 10:11
Jesus is described as the "good shepherd" who lays down his life for the sheep, contrasting with the elders' role emphasized by Paul in caring for the church.
John 10:11: I am the good shepherd: the good shepherd giveth his life for the sheep.
Contradiction with 1 Peter 5:2-3
Leaders are advised to shepherd willingly without compulsion, highlighting a potential contradiction in the approach to leadership in the church as mentioned in Acts 20:28.
1 Peter 5:2-3: Feed the flock of God which is among you, taking the oversight [thereof], not by constraint, but willingly; not for filthy lucre, but of a ready mind; [which...: or, as much as in you is]
Contradiction with Matthew 23:8
Jesus tells His disciples not to be called "Rabbi," for one is their Teacher, potentially conflicting with the role of oversight and leadership in Acts 20:28.
Matthew 23:8: But be not ye called Rabbi: for one is your Master, [even] Christ; and all ye are brethren.
Contradiction with Hebrews 13:17
This verse emphasizes obedience to leaders, whereas Acts 20:28 puts responsibility on the leaders to oversee the church, showing a different perspective on roles and responsibilities.
Hebrews 13:17: Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that [is] unprofitable for you. [have...: or, guide]
Paradox #1
The potential doctrinal conflict with Acts 20:28 might arise around the concept of the nature of God and the relationship between God and Jesus. Some interpretations might find inconsistency in how the verse refers to who purchased the church, which can lead to debates about the divinity of Christ and the nature of the Trinity. However, it often depends on specific theological perspectives and interpretations.
