The home of a Christian couple charged with their infant daughter's death after they refused to seek medical attention is littered with signs condemning evil and ordering people to seek God.

The hand-painted signs are nailed to fences surrounding Seth Welch and Tatiana Fusari's Michigan farm and affixed to trees in their front yard.

Welch painted the red, white and blue bible verse signs more than a year ago, asking his Facebook friends at the time to send him scripture ideas.

'What verses have really stuck in your head, either as an unbeliever coming to Christ, or as a motivator to you as a Christian,' he posted.

The signs scattered across the yard include bible verses and warnings telling people to 'repent believe obey'.

Other signs read: 'Blessed are the peacemakers', 'Every knee shall bow and every throne will confess to God' and 'God knows what you need before you ask Him'.

Welch also painted religious messages in large white letters across his wooden fence.

'My kingdom is not of this world,' one message read, while another quoted Matthew 6:10: 'His kingdom comes, his will be done'.

Welch often shared photos of the placards on his Facebook page, along with dozens of images of highlighted verses in his bible.

Photos from inside the couple's home show handmade wooden desks and chairs, bare walls and images of their young children working on crafts- they have two older children. Welch often posted videos criticizing worldly things and encouraging believers to 'live off the grid'.

Welch and his wife, who is believed to be pregnant with their fourth child, were charged on Monday with felony murder and first-degree child abuse after Welch called 911 to say he found his 10-month-old daughter Mary dead in her crib.

First responders said the child had sunken eyes and cheeks and felt cold to the touch. An autopsy revealed that she died of malnutrition and dehydration due to neglect by adult caregivers.

Welch and Fusari, both 27, reportedly confessed to police that they noticed their daughter was skinny and underweight as early as a month before her death but did not seek medical help 'for fear of having Child Protective Services called, lack of faith and trust in medical services and religious reasons'.

In a bizarre rant posted two weeks before Mary died, Welch lashed out at doctors calling them 'skillful magicians and experts in charm'.

In another post he labeled doctors 'the priests of the medical cult'.

'The righteous shall live by faith,' he continued. 'It's God who is sovereign over disease and those sorts of things and, of course, ultimately deaths.'

Welch also hit back at critics who attacked him and his wife for not vaccinating their three children.

'It didn't seem smart that you would be saving people who weren't the fittest,' he said in a video. 'If evolution believes in survival of the fittest, why are we vaccinating everybody? Shouldn't we just let the weak die off and let the strong survive?'

The couple's two other children, a four-year-old girl named Elizabeth and two-year-old boy named John, were removed from the home and, according to a Facebook post from Welch, are being cared for by grandparents.

'Heart is about shattered right now,' he wrote on August 2, the day his youngest child was found dead.

'Woke up to Mary dead in her bed this morning - this evening had our children removed and placed on "no contact" because Tati and I are the worst parents ever - Thankfully they are with grandma and grandpa. Just numb inside right now. And I'm really enjoying the loving embrace of an isolation cell from the cops and government employees who keep assuring me "they are only here to help".'

The couple made their first court appearance on Monday where Fusari wept as a judge announced the charges. Welch stared at the judge with his mouth hanging open.

The parents are being held without bond and court records do not list lawyers who can speak on their behalf.

The couple could face life in prison without parole, if convicted of felony murder. They are back in court on August 20.
